To access all the materials and models go into the .blend file

There you will find all models with all LODs and materials

Textures are packed into the .blend file but I include them separately too

These two files are not necessary in blender they are smoothness maps to Unity, but when you import them to blender nothing is going to change

Textures for Bright and Dark pieces are the same except the base color

Pieces with materials have 2 separate materials on each model: Felt which is plain green material and actual material

I include all the models and shaders in .fbx format they are located in the FBX folder

Models in the .fbx format are without textures, so to have them you need to import Materials with Textures folder too

For easy import to Unity there is Unity package file which you need to just drag and drop into your unity

I recommend using Unity 2022.3.2f1 which I was using
