Support material property assignment #318
Description
Extended ApplyMaterialProperties to loop through all properties in the provided JObject and set them directly on the material if they match a known property (e.g., _Color, _MainTex, etc.). Now supports direct assignment of color, float, and texture properties using simple JSON structures, such as: { "_Color": [0, 1, 0, 1] } for albedo color
{ "_Glossiness": 0.5 } for smoothness
{ "_MainTex": "Assets/Textures/MyTex.png" } for textures Retained backward compatibility with the previous structured property format (color, float, texture objects). This change enables more flexible and user-friendly material creation and modification via automation and external tools. Fixes issues where material color and other properties could not be set from automation.
