Plugin Upd | 3d Rad Exporter

This is the most common version of the exporter, designed to bridge SketchUp models to the 3D Rad engine.

The Export Process: Once loaded, the plugin sits under File > Export > Rad Scene (.rad). 3d rad exporter plugin

4.2 Coordinate System Transformation
3D modeling software (e.g., Blender) typically uses a Z-up coordinate system, while many physics engines use Y-up. The plugin automatically applies the necessary rotation matrices during export to align with the simulation coordinate frame. This is the most common version of the

Base Color → Diffuse texture.
Metallic → Cannot be directly translated. A common heuristic is to convert high metallic values (e.g., >0.8) into a dark diffuse map with a bright specular map.
Roughness → Inverted and mapped to Specular exponent (roughness of 0.2 becomes a tight specular highlight; roughness of 0.8 becomes a broad, dull highlight).
Normal Map → Directly passed to the Bump slot, but the plugin must ensure the texture uses the correct DX (DirectX) normal map format (Y-axis flipped) rather than OpenGL format.

Goal: Export a fully textured, drivable car with rotating wheels and a glass shader. Base Color  → Diffuse texture
