Skybox effects broken with latest Raze backend merge

[Nash]

With GZDoom 4.10:

- Cloud texture is scrolled by the shader
- There's a fog effect that hides the skybox's seam

With gc8fe07404

- Cloud no longer scrolls
- Fog is missing

Started happening after this Raze backend update: https://github.com/ZDoom/gzdoom/commit/ ... 2b5657aeb3

As a continuation from what was discovered on Discord,

I can confirm that

- this only happens with a diffuse-only material shader
- therefore, adding a flat/non-transformative normal and specular map DOES successfully apply the custom material shader, AND also "fixes" the fog not being applied to the texture.

Code: Select all

Material Texture "textures/sky_back.png"
{
	Shader "shaders/Materials/Sky.fp"
	Speed 0.2

	Normal "materials/FlatNormalMap.png"
	Specular "materials/NoSpecularMap.png"
}

Material Texture "textures/sky_front.png"
{
	Shader "shaders/Materials/Sky.fp"
	
	Normal "materials/FlatNormalMap.png"
	Specular "materials/NoSpecularMap.png"
}

Did some more testing, and it's just not my own projects that are broken from this. All of Tormentor667's remaster projects are also broken because they make extensive use of user shaders.

Generally, any mod that assigns a shader to a texture/sprite/whatever that only has a diffuse layer, will have its visuals broken.

Should be fixed now.
