Question How can I import existing Blender prefab's materials into Shader Graph

I have a blender model with several materials and textures with a standard shader

I want to change the shader to do something like a see-through wall

Code (CSharp):

Or just simply change the transparency of the model,

If I try replacing any materials in the model, I lose the texture on my model.

I dont want to go through the process and re-add the materials and textures to the model from scratch since there is a few of them

How can I import/create a shader graph with existing materials in the blender model and modify this shader graph?

Thanks

 

If you want a custom shader you have to extract the materials from the model and put the shader on it. The default shaders aren't shader graph ones

 

There's no facility for that. Blender integration in Unity simply consists of a python script that Unity tells Blender to run, and that script exports your blend file as an FBX, which Unity imports.

All the material and shader graph stuff is outside of that domain. Here's some more random Blender integration notes:

Unity imports Blender3D objects as FBX via a little Python script:

The Python script that Unity uses (substitute your Unity version number or search) to import:

./Hub/Editor/2020.2.1f1/Unity.app/Contents/Tools/Unity-BlenderToFBX.py
