Alone in the dark -- "ghostly halos" bugs #323

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When I use flashlight or I see a flash on the street every objects shows 
ghostly halos.

Just look at my pictures. I specially created it in "CLOSE UP"

It happens with any settings on all revisions, and with all emulators: Makaron 
& DEmul & Chankast & NullDC !!!

Bad thing!

Is it possible to fix somehow? Cuz I just would very like play DC's version of 
Alone in the Dark. Graphics here better than PC & PS2 versions.

Thanks!

There's some odd glitching on the title screen too, where the light moves 
around the game logo. Might be related.

THE NEW BUGS DETECTED! STARTS WITH r108.

r107-108 - gave us a some new bugs - more halos and bright colors on 
backgrounds. 

Black-shading effects when watching a game's movie!

For r108 more guilt ofcourse. 
but r107 starts something, I think.

NOTE:
Pitch Black effects in movies and flashlight's bug happens when we use the best 
Zbuffer - D24S8+FPE (Slow,Good Precision) the flashlight shows normal when we 
use ZBuffer...Mode2. 
Or when we use VSYNC the flashlight shows normal or half-normal.

Here I posted some pictures.

@Mr.PsyMan

Ofcourse I'm sure becouse on r107 - it was half-normal (I mean about new bugs), 
but I saw problem with flashlights just a little. It is no happens before r107 
- r108

r108 - guilty 100%

Try on Zbuffer D24S8+FPE (Slow,Good Precision)and "Sort - triangle"

Maybe the game had the same bugs before 107 too? It's more likely that you 
messed with the PVR options and the changes resulted in this...

For example, on r104 those new bugs is not exist.

P.S. 2

1) "The transparent effect" and "Black-shading" and "More intensive brightness 
for backgrounds and for ghostly halos" - is a new bugs.

2) The "ghostly halos"  existed  allways on Nulldc - on all versions - it is 
very old bugs.

Unless someone compiles and tries revisions 106 and 108 on his own to verify 
that revision 108 is to blame I'm not gonna look at the problem.

@Mr.PsyMan,

What do you mean? o_0

I dont understand.

You dont see those bugs in your own tests? Very strange. 

Do you think it is r105 or 106 ?

I have no idea.

What I do know is that revision 107 and 108 had completely unrelated changes. 
They should have nothing to do with the bugs you encounter.

Alright you need just forget r107... (In there I seen just a little problems 
with flashlight when Vsinc was disabled and thats why I suspected it) . Sorry 
if you disoriented. I just assumed. Very maybe I'm wrong. 

The real bugs (new bugs) starts on r108 - 100%garantee. I'm sure absolutely. 
Cuz on r107 those bugs not exists. -----> I mean "The transparent effect" and 
"Black-shading" and "More intensive brightness for backgrounds and for ghostly 
halos"
 - it starts with r108 only!

We need to focus on r108.

Mr.PsyMan, 

I found something about "Black-shading" in r108....

It is problem with "Sort"

When I use Sort: Triangle - I see "Black-shading"

When I use Sort: Per Strip or Sort:OFF - the "Black-shading" disappears.

Maybe it will be helpful.

P.S.

About "The transparent effect" and other cant tell something new... yet.

Listen! I have idea how to fix ghostly halos bug! Just look at my pictures – 
for different revisions. The new "ghostly-halos" appeared on one picture not so 
long time ago. In the same time  the brightness of backgrounds (or pixel of 
background) become more intensive. I suspect, here we can see the clue. 

So, maybe in the code we must change the function controling levels brightness 
for pixels of background of something like that. 

I think the new bug demonstrate us one thing. If "ghostly halos" it could be 
brighter than earlier, that means it could becomes darker if we change 
something to reverse direction.

What did you think?

P.S. Or we should create a special full-screen "shadows overlay".

NOTE:

Please, very carefully look at the screenshots. Compare them. You'll see a 
clue, I think.

That's r104 vs r108. I see no difference, nor did I ever ecounter some of your 
bugs. Make sure that you're using a clean build please, and of course 
non-optimzed when reporting.

@KrossX3,
You showed me a result when you turn OFF "Opacity patch level" (you compiled 
r108 with "OFF" by default, but  in my version it was "ON" by default)- the new 
bugs is dissapear. I know. Now I have no problem.

It was not my own compile. I dont  know how I can do it. I hear something about 
programms for compiling but I never used it before. But I can try to learn 
ofcourse. I'm not an programmer and in that is my fault. Ok, never mind . 

BUT! How about using the flash light? "Ghostly halos" is still. Try use 
flashlight and  you will see  the old ghostly halos on objects. It happens with 
ALL versions of NullDC!

So, I need to correct my idea (or just question)

Look:

Fact: 
When turn ON "Opacity patch level"   we see a new bugs with halos an with 
bright of backgrounds

Fact:
When turn OFF "Opacity patch level"  - new bugs dissapears.

Idea/question for solution:
So maybe we can do something else with "Opacity patch level" when ghostly halos 
will dissapear absolutely.

Nobody want to tell me something about "ghostly halos" as if this problem never 
existed?

P.S.

What I need from this list  to start learning how to compile?

      CollabNet (professionally supported and certified by CollabNet; requires registration)
    *

      SlikSVN (32- and 64-bit client MSI; maintained by Bert Huijben, SharpSvn project)

The "opacity patch level" hack has been removed already since r115, so just 
forget about it.

For compiling, there's already a guide in the wiki:
http://nulldc.emudev.org/wiki/doku.php?id=guides:build:windows

And yes, the "halos" are a problem. The "new bugs" were in question though.

any news about the alone in the dark bugs? also in the newwer nulldc versions 
the cutscenes no longer can be seen it shust playing in black screen so any way 
somebay can fix this bugs in newer versions? regards

I doubt that.
I think, you should wait a new version by another emulator. It's Demul based on 
DX11 (But you need a fast CPu and new videocard) 

By now on Demul 5.7 with DX11 video plugin this problem half-solved  . The 
"ghost halos" is not exist now, but the game crashes when videoclips. But it is 
just yet...
