The Legend of Zelda: Breath of the Wild [ALZ#01]

[ActualMandM]

[Moved to #137]

Since this is a pretty huge game, a lot of work will have to be put into the graphic packs. Issues with the game can easily appear when working on the graphic packs for this game.

Main:

• In certain cinematics the depth of field is completely black when format 0x816 is excluded (320x180)
• Bloom becomes all pixelated and randomly disappears when format 0x816 is upscaled (320x180)
• So called "red filter" missing in certain areas (320x180)
• Fix shadow upscaling

Optional:

• [x] Figure out how to fix AMD circle lights (Nesquick found the file... now we need someone with AMD to fix)
• [x] Fix tiling issue, since apparently a NVIDIA Inspector setting edit doesn't fix it completely (shader)
• [x] Fix the majority of the Z-fighting, if possible (Cemu issue)
• [x] Fix the teleport animation

[ActualMandM]

For enhancements (and performance): Seems like there's more than two shadow resolutions, according to SunBroDave. http://www.neogaf.com/forum/showpost.php?p=231879693&postcount=1668

As far as I can tell this is the shadow rendering path for gameplay. 720x720 long shadows > (360x360 long shadows slice?) ->640x360 blur of shadow texture > 192x192 (light/dark grading)

Cut scenes have a per scene lighting as well (ie gl_FragCoord that needs a PS fix, somebody get me a 1.7.4 shader dump plz :P) . Player perspective is roughly the resolution of the projection of shadow textures 720 (tv res) ->640 (buffer res) When we uncomment that part for fixing buffer effects shadows look worse, the soft/blur pass is done in 640x360.

720x720 shadows 2d array 3 slices. 3 detail levels. Left distant, middle closest, right medum distance (flipped wrong way) . Red circle is Link So scaling 720 will increase resolution of all these

360x360 shadows may just be the slices of 720, or 360 may be used for performance scaling.

2048x2048 Link light/shadow projection cut scene? Unverified. 1280x720 depth component projection player perspective 640x360 depth component projection player perspective, 2d blur/soften of toon shader, light projection spheres 320x180 depth component projection player perspective, bloom pass. 240x135 depth componet projection player perspective 160x90 depth component projection player perspective, medium detail bloom pass. , 80x45 depth component projection player perspective 192x192, 2d depth maps top down 64x64 depth component projection, 2d depth maps top down 40x22 low detail bloom pass.

64x64 > 32x32>16x16>8x8 cube map lod (world reflections)

512x512 format 0x005 Ground geometry LOD from height map, almost like old voxel engines. Should be interesting when we have texture modding.

1024x1024 + mipchain shrine volumetric fog ?

3x3, 6x6, 12x12 24x24 48x48 96x96 Unknown, noise pass, sprites? 3x3 is possible a noise cube map? 48 and 96 are probably GUI, breaks mini map when scaling.

64x45, 32x24, 16x12, 8x6, 4x3, 2x2 Lods of the same rendering, colour grading?

Texture dump also gives us 1024x1024, and 256x256 format 0005 textures, used for stencil shadows in other games. But I haven't seen/verified them in-game as actual shadows. 255x256 looks like its being used for lots of different things.

[Tyrindor]

You deleted my comment about the graphic pack not working with the new H264 workaround, yet it is not listed as a "known issue". Green screen when playing H264 videos, disabling the graphic pack fixes it.

https://sshnuke.net/cemuhook/

[ActualMandM]

@Tyrindor the next cemu hook update should fix the issue

[ActualMandM]

@Tyrindor 0.3.2.1 was just released, try it now

[Tyrindor]

Yup, H264 videos work now. Thanks.

Hopefully the lighting/effects bug is fixable soon.

[ActualMandM]

Lighting/Effects would probably have to be via shader edits, which'll be fun

[ActualMandM]

1.7.4 has been release..guess it's time for shader edits.

[Darkemaste]

Awesome, 640x360 confirmed to break more than just heatwaves when uncommented. Also it seems fog uses 720x360. (discovered in GPUPerfStudio in 1.7.3)

[getdls]

640x360 upres issues I've seen Breaks normal mapping, example light on ground when opening chests and wall lights -> Fixed w PS edit "Breaks" distant blur so blending gets too sharp, introduces artifacts in edges. Example church roof.. Looks like an L shaped noise texture, probably 3x3. Cut-scenes are however the worst.. they combine all of the above with DOF issues further muddying the waters.

[getdls]

This fixes lights for shrine of Resurrection while scaling 640x360 for dof/shadows etc.

• Bath light, DOF bathlight
• Normal maps ground when opening chests
• Wall torches

It looks like a generic approach can be taken as long as you're careful to scale the right shaders. So anyone can dig in.. its more about persistence from here on :) Look for any light source shader, dump, copy paste. I'll leave it here instead of committing. If anyone can confirm it works for AMD/doesn't break a bunch of stuff.. feel free to stick it in the repo.

edit Old files removed, please use repo files after commit, they have been tested by some nice ppl. There are at two dependencies

• rules.txt must scale resolutions in proportion,
• Resolution must be manually set per shader (we can fix this later).

I'm going after AO and the distant horizon artifacts, AO doesn't increase sample amount.

[ActualMandM]

@getdls Some people found shaders not scaled. (I don't know what shaders they are, sadly) Cooking Pots are broken, reported by Loli Co. and JoelAlone on official discord

Shrine teleport is broken, reported by JoelAlone on discord

Shrine Monk Barrier, reported by Kieron on discord

Heart Piece, reported by flocker on discord

This one was also reported by flocker on discord

shader edits aren't being used in that screenshot

Someone noted that the fire on the torch disappeared for them

NiagA on GBAtemp reported Tower lighting issues

[ActualMandM]

I don't understand how I would have broken bloom. Apparently people who use your fixed graphic packs get bloom, but those who use the packs in the repo have no bloom. And yet it uses pretty much the same exact values. Only thing I tried was adding format exclusions to make the bloom not scale, both title screen and in-game. Nobody gets bloom because of these format exclusions. Is it because of q-res being scaled in the repo but not in the fixed packs? I've reverted those changes already, but it gives the pixelated bloom that everyone hates. I honestly don't know at this point. Either way, I'm just gonna take a break from this.

Images are by Kieron on the official Discord Repo ones with format exclusion: Your fix graphic pack:

Edit: Seems like I messed something up when scaling the images. Kieron found what seems to be the same issue that NiagA found, but can't find it on your pack. I give up. I'll leave BotW up to you guys. I'll be focusing on other games instead.

[getdls]

v0.3

• Tower lights (probably fixed in prev version)
• Cooking fires, grass fires
• Magnetic temple lights, and possible some other temples if they re-use the same code.
• Temple of time statue light

edit Old files removed, please use repo files after commit, they have been tested by some nice ppl.

I'm not scaling any of the bloom resolutions, nor AO right now . So far I haven't seen any improvements in other fx that makes it worth it. Could be that... or what you're seeing bloom + shader fix? update Now includes temple of time heart fix..

Any new issues, please report, and include a save file... I'd like to avoid spoilers as much as possible.

[MaxG3D]

@slashiee Yes, the scaling of the bloom offset is what causing the bloom to be pixelated. If you want to scale the size of the bloom like that, you would also need to find the weights in the code (Assuming the big N is using the Gaussian Bloom). It's an easy fix, either delete the scaling code lines or replace them with default resolutions:

[TextureRedefine] #q-res1 width = 320 height = 180

formatsExcluded = 0x816,0x01a #Completely gets rid of bloom

overwriteWidth = 320 overwriteHeight = 180

[TextureRedefine] #q-res2 width = 320 height = 145 overwriteWidth = 320 overwriteHeight = 145

[TextureRedefine] #q-res3 width = 320 height = 144 overwriteWidth = 320 overwriteHeight = 144

[TextureRedefine] #o-res1 width = 160 height = 90 overwriteWidth = 160 overwriteHeight = 90

EDIT: One could also comment those lines, as so many people on Discord so gracefully corrected me.

[ActualMandM]

@getdls I've just added the new shaders with commit e269ac3. For those reading this, please send thanks to him, not me. I've also said in #gfx_packs (and #botw_discussion) for the official discord to send a save file for new issues.

@MaxG3D The issue is not the pixelated bloom, the issue is that excluding the bloom makes it disappear altogether. Values commented out in f9af446.

[Tyrindor]

The new commits are working really well for me, it's definitely getting there. I have noticed that water ripples change color at certain camera angles when swimming, and it doesn't seem to happen with the pack disabled. Really minor though.

[getdls]

These are two "enhancement" packs in one zip. They show how to scale 640/ DOF to arbitrary resolution and still keep light fixes working. Nothing new is fixed, it just gives some minor improvements and possible breaks other stuff.

Since they scale up 640, things limited by that viewport prettied up abit.

• 1440p DOF "fixes" horizon and grass artifacts less shimmering of light effects and DOF, good text scaling.
• 1080p DOF "fixes" horizon and grass artifacts, but its "just" HD.

Edit 3 Attached wrong 1440 version last night, sorry abt that, lights should work now.
4k/8k replaced with 1080 and 1440 only clean horizon versions should be more useful for actual gaming.. and I'm guessing what most ppl want.

edit Old files removed, please use repo files after commit, they have been tested by some nice ppl.

I'm hoping the 4k/8k version can be used in combination with AO fixes and some new blur implementation eventually.

[motionloops]

Hey Guys, have you tried increasing the depthbuffer accuracy (change it from 16bit to 32bit)? This could help fix some of the issue with distant terrain flickering aka Z-fighting. The Cemu changelog for 1.7.4 mentions "'overwriteFormat' and allows to respecify the data format of a texture. For example, using this property it's possible to turn a 16bit depthbuffer into a 32bit depthbuffer" but it doesn't say how. I also noticed that the low lying distant clouds in the terrain are missing so this might fix that as well.

[ActualMandM]

I tried changing the game format from 0x019 to 0x816, Only saw regression

[getdls]

Yea that and some of the atmospheric / shadow/texture layer blending def could use some higher precision. I was going to try it out for fixing Xenogears bloom, but I'd love to see some examples where it works and not just pads the values.

As for depth, can we get higher precision (apart from increasing resolution) and still use Wiiu features? Depth is 0x005 afaik and unorm has higher precision than float 32 at 0-1 values. GX2_SURFACE_FORMAT_UNORM_R16 = 0x05, Let's hope I'm wrong here..

[ActualMandM]

@Tyrindor Issue seems to be a Cemu issue, reznoire 1.7.4 preview video has it as well https://youtu.be/B548VlSXykI?t=22

[CubanLegend]

@getdls thank you for the 8k DOF, its performance heavy but the research leading to it's fix is appreciated. :)

Would you happen to be able to check out removing the remaining hud elements like the hearts and the horse sprint spurs? Just curious is that's something you might like to do, it would make for greater immersion in the Pro HUD mode, and would also double as a great start to a proper BoTW CEMU photomode.

[ActualMandM]

[motionloops]

I took a look at the depth buffer using Nvidia's Nsight and Cemu is already using a 32 bit depth component. But it seems like all the precision is towards the near clip plane of the buffer. So in botw, for example distant objects have issues with Z-fighting and missing low lying clouds and fog in the distant terrain. This leads me to believe that the depth value is not being encoded properly (https://developer.nvidia.com/content/depth-precision-visualized). I'm a graphics developer but i know almost nothing about emulation so i could be totally wrong about this. Either way I'm just trying to help by pointing out a possible issue. Anyone know how to get in touch with Exzap or one of the other cemu dev. Tried discord but I'm guessing he's being inundated with questions.

[RedDevilEvo]

Hi guys ! how could i resolve those light glitch? I have the last 1080p graphique pack. I love Link but a twin is too much lol!..

[motionloops]

@RedDevilEvo Delete then update your graphics pack, I'm using the latest one and i don't have those issues.

[RedDevilEvo]

@motionloops I just tried but still the same. 1080p pack. I did not have a 4k monitor so.. :/

[ActualMandM]

Make sure that the text files with the long names are in the same folder as the 1080p pack

[RedDevilEvo]

@slashiee It worked thanks a lot !

If anyone got the same glitch .. be sure your pack look like this. haha

[ActualMandM]

@getdls

[getdls]

@slashiee

pretty plz? with sugar on top

[JoelAlone]

@getdls save.zip Save with broken heatwaves

[getdls]

Issue is intermittent, not much I can do about it. From what I can see, the PS has some delay when viewport doesn't match half size, if I just stand still, it loads after about 8 seconds, and then everything works fine. BOTW uses lazy evaluation of some effects, for example the wall lights.

• Killing the wave effect removes the repeating texture issue, but also disables the effect.
• Doubling the size starts the effect directly, but then breaks it when the delay loads in.

[JoelAlone]

@getdls Can you tell me how to kill this effect?

[getdls]

Any way that stops the resource from being used should work. ie Dump the texture to get ID and type, work backwards from there to the PS and remove the texture line from the shader.

[getdls]

This is an updated AA removal that also fixes the issues with horizon and grass. Files are resolution independent so just drag and drop into any pack. To avoid any confusion, AA removal is meant for ppl using their GPU drivers for AA , not to replace the in game AA with a new version.

Botw_AAremovalV2.zip

• No known issues, but some testing would be good before committing.
• Potential risks are far away things that should be hidden are now visible, or some gradients removed but so far what I've seen it matches Cemu w/o any graphic packs active.

Happy Easter for anyone who celebrates!

[getdls]

Commit fixes Dof masking, used for near field blur, haze blur, water effects etc. This works by only scaling depth for 320, 160, 80, ie not breaking bloom

AAremovalV2 was also added

https://github.com/slashiee/cemu_graphic_packs/commit/693778d88ade1c1eb4277c88ffde8ae352fedb0a

[ActualMandM]

1800p pack added witch 76786a1cad71d73c428252b53e62506a368fe0af, please thank @JoelAlone for making the 1800p pack itself, saved me some time with making 1800p packs altogether

I heard there's a new graphical issue with 1.7.5, but I haven't messed with BotW much this update. If there's anyone that can confirm this graphical issue and can upload a save file to it, it would be gladly appreciated.

[LUCKASSs]

Hello guys, and sorry for the shitpost, but how I can use these files : http://prntscr.com/f117wv

And how I can use these + another rules.txt like this ? : http://prntscr.com/f117sv

BTW I use the 1.7.5, I can upload what you want from It.

thx !

[RedDevilEvo]

Read the comment i did a post for that.

Make a txt file for all of thoses with the name you see with all of those number.

And pute it on your CEMU/graphiquepack folder

Create a new folder in and give it the name you want. And drop all your txt files in it.

Should look like my post i did here just look up

[LUCKASSs]

@RedDevilEvo Yeah I have already do that : http://prntscr.com/f121u2

btw, why people want to remove AA ?

[RedDevilEvo]

Yeah on a different folder. And you have to activate your mods ( pack ) via CEMU

[LUCKASSs]

@RedDevilEvo ok thx, and Why people want to remove the AA ? it make the game much better ?

[RedDevilEvo]

I dont know i'm still playing with the AA. Maybe it's a performance issue. Low fps or visual glitch i dont know.

[JoelAlone]

BoTW's AA is really bad in comparison to SMAA or even FXAA, that's why many people remove and replace it with other AA method.

[ActualMandM]

Updates to BotW pack will be postponed until 1.7.6, we don't want to work on shader edits just for it to be completely wiped with the next update. It would just be a waste of effort. Please don't report issues about lighting issues when 1.7.6 releases please. But if it happens to be a new lighting issue that wasn't fixed though, then please do report it.

[amunozj]

Hi! First of all thank you so much for all the work you have put into the graphic packs. I wanted to ask you a quick question. The performance 540p pack is too severe a reduction and the quality 1080 is too demanding. I wish there was an in-between option. When I run the game without packs it has the perfect resolution, but I was wondering if I could benefit from all your other fixes. Is there an easy way to modify your packs so that they don't change resolution, but include the rest of the things? Thank you!

[BreakPoints]

@amunozj The fixes here are all fixes for bugs that happen due to overriding the default resolution. If you aren't using any graphics packs then you don't need any fixes, it should be less buggy than even these graphics packs with their fixes.
