Standard Shader references_RainSheet although it does not use it

[wilk-polarny]

Hi!,

I've recently upgraded to the Standard Shader 2.1 and noticed that there are a lot of textures referenced/included, that are not needed at all.
For example: The Rain Sheet (8MB) gets referenced and ultimately included in a build, even though the rain feature is not in use.

It would be even better if the shader tooling would only set the required maps whenever corresponding feature is enabled/used.

Thanks!

This is a known issue but fixing it is complicated. It requires hooking into the build process and iterating over included materials to remove unused references based on toggle states. I'm not sure if this will wipe the references from the assets in the project, or just a version being included in the build, but if it does then it would break any materials that may want those options toggled on later. I'll look into this.

I understand, yea. As a current workaround in my project, I simply reduced the resolution of the texture significantly to reduce the impact on the build size.

The solution would probably have to be hooks, if you don't want to change the whole architecture like other shaders - like some that are modular and generate and assign new, individually stripped (unused modules, maps, etc.) shaders at build time.
