Describe any usage details

I've redone the World Shader so the Sky and Global Illumination look more like the trailers from Mojang. This is perfect for use with the Barebones Texture Pack.

Parts of the changes are:

• Separated GI from Sky, so you can change the "Skybox" without changing the GI (hence the more trailer feeling).
• Modified current gradients to feel more like the trailers.
• Created a better Star System and Fixed the time-passing issue, it now works on time-lapses.
• Created a Procedural Day/Night Cycle with an interchanging Sun and Moon.
• Added a Volume Absorption to Help with the Trailer Feeling (Turn off Light Tree in newer blender versions).
• Added a Cloud Movement according to Time.
• Created a new Water Shader that should resemble the Trailers a little.

I tried my best to make the shader readable. Changes are located on: Shader Tab > World Volume > Shader Tab Sun/Moon > Transform Rotation & Custom Property for Extra Rotation Control & Shaders Render Tab > Color Management

I'll make a youtube tutorial explaining in depth the changes and how to recreate the Trailer Style on my YouTube in the future too. For now, you can dissect the changes I made on the file Not sure on how to send the file so here's the Drive link for it. https://drive.google.com/file/d/1CsUnoDbMkXsSGKEB9-5KwWnyXCa1Lvqx/view?usp=drive_link

Looks really nice @leonardofries!

I'm curious, do you think at this moment that this shader setup would be appropriate for all users - Ie replacing the current one entirely, or that it should be an additional option?

The other detail is that we want to support as old versions of blender as possible - when I get a chance I'll see how far I can downgrade or, but are you aware of which version of blender you saved it on/any features it's using which would prevent it from being used in the 2.8x or 3.x series? Not necessarily a blocker, but is a consideration.

Looking forward to the tutorial - and appreciate your patience while we review.

I think we could add this as a separate "trailer" option, since this is more geared for a trailer style, but then backport parts of it the current "in-game" sky

[leonardofries]

@TheDuckCow It can be used by all players without problems. I made the whole day and night cycle for that. I have given a lot of creative control over the entire thing, so you can turn the Global Illumination on and off or change the strength of it. As far as I'm concerned the default values I left at will make the render look like the trailers when used with the Barebones texture pack, but should look good on the default textures too.

And about Backwards compatibility, that's something to be checked, I don't think it would go all the way to 2.8, but it can go back a couple versions with no issues

[TheDuckCow]

Ok that's a good suggestion @StandingPadAnimations, giving it as another option would also mitigate the need to get it working too far back in terms of blender versions. I'm not sure how common it would be, but perhaps we could actually generalize the system such that we have a skies folder for different sky setups, allowing users to create their own custom ones. A little extra work, but would make it more feasible to merge this work in sooner.

Uploading your source blend after zipping it up, so we have a longer term record of it (in case the drive link dies) Proj Terr - Barebones.blend.zip

Demo file is really nice @leonardofries! Curious, have you rendered this out and shared somewhere? Would love a to link to it.

@TheDuckCow I'll have a video by tomorrow. For now I only have these weird test images and the ones on the original post

lol wonderful, looking forward to it haha

Good news and not so bad news. It seems to be fully compatible up to 2.8. But one thing will be missing. I wasn't around the 2.8 era, I think I came in at 2.83 and only learned it fully at 2.9. So, not sure on this one, but you can't add a Input to Rotation on the Mapping Node, so I could not think of a way of making the stars rotate in the background as the time passes. The rest works fine. I'll be uploading these files soon

Default Texture Pack Checks Out for me!

[leonardofries]

Works exactly the same as in blender 4.4 except for Rotating Stars As The Time Pass and the Truncate Modulo that fixes the time thing. I don't have time to fix these, but the Truncate Modulo can be made with the Math Nodes Available. And I'm pretty sure theres a way to animate the rotation of the noise texture (ie: stars)
