    Hello, I can't figure out how to write texture or other data (like JSON) inside a material in the Unity engine, How can i do that and is it possible to write JSON data?

    You want a material to write to JSON? Not possible. Materials, or more specifically the HLSL shader code, runs entirely on the GPU and the only data it writes is the color for each pixel of the render target it's visible in.

    If you want the material inspector in the editor to write to JSON, that is possible. You would need to write a custom editor for your material.
