Advanced Curtain Shader
Is it also for Eevee?
Advanced Curtain Shader currently is for Cycles only
Does it use a PBR workflow?
You can use diffuse, specular and normal maps (as vector displacement). Glossiness/Roughness is managed automatically by the shader
Where is the normal map input?
Use your normal maps as vector displacement in the material output
Does it include all of the materials in the example images?
Only the shader itself is included. That' s beyond my control, because most of the fabric textures available don' t have a royalty-free license: they cannot be distributed along the file
