How to set Shader material as default material and auto apply textures to that material?

[klownkaids-commits]

I'm currently working on a game and the documentation for funcgodot isn't helping me much in terms of understanding. I have a shader that applies some PlayStation 1 looks to the textures in my game. I could apply the shader individually to each material override but overtime that will be long and tedious after each map rebuild. I was wondering if there was any way to set the shadermaterial as the base texture and then through that have a variable that applies the texture used in trenchbroom? I want to know so I'm not sitting here twiddling my thumbs trying to find this out lol. Below is the image of how the material looks in the inspector.

Yes, in your map settings, set your default material there. You will then want to set the Default Material Albedo Uniform to map to your albedo for your shader. You can also add additional textures with the Shader Material Uniform Map Patterns in there too. This is covered in the textures page of the documentation.

ok I think I understand, but just for a deeper understanding because the documentation is still confusing me a little bit, how exactly do I setup the textures to apply in the material albedo uniform? do I have to rename my textures in Godot orrrr. sorry I'm a little lost. Any help would be appreciated!!

You shouldn't need to rename it. For the albedo uniform, it automatically detects the texture, you just need to set the albedo uniform so it matches 1:1 with the uniform for the shader material. Behind the scenes it is calling set_shader_parameter(). You might need to rename the albedo uniform to be texture_albedo in your shader(iirc that's what it matches against. @RhapsodyInGeek can probably confirm) I'm misremembering, you just set the uniform value to match what it is in your shader.

https://docs.godotengine.org/en/stable/classes/class_shadermaterial.html#class-shadermaterial-method-set-shader-parameter

You would only need to rename your textures if you wanted to apply multiple uniforms. When doing that it pattern matches. As an example say we have the pattern %s_n to mark normal maps. If we had a texture named texture.png, it will also try to match texture_n.png and then apply it as a shader parameter to whatever key it has. For your usecase with only an albedo uniform this isn't important.

Okay so I have set the shader material into the map settings. For last bit of clarification because I'm still a little confused on what to write. What name am I putting into the circled area? I'm sorry I'm new to all of this stuff!! Any help is greatly appreciated

Probably albedo_texture. Look inside the actual shader itself at the top will be a bunch of uniforms. Whatever the one that reads like an albedo texture, is the one you use there

I typed in the name I saw which is texture_albedo into the default material albedo for funcgodot settings and it did nothing 😭 here are the photos below to show this. Is there any step I'm missing or did I do something wrong? Again thank you for your kind help!!

When you build a map it doesn't override any materials that have already been generated. Make sure you've deleted those materials if you haven't already

THANK YOU it finally works!!!!! I am very appreciative of your help If I have any more questions about other things I will make sure to come back here in the future!!!
