The 3D Rad exporter plugin is a specialized add-on developed to convert 3D models from external applications—specifically and, through community efforts, Blender —into the DirectX (.x) file format. The 3D Rad engine relies heavily on this format to load meshes, textures, and basic rigging.
To help me tailor any troubleshooting steps or specific workflows for your project, please let me know:
In SketchUp, install it via the Extension Manager (Window > Extension Manager > Install Extension). Do not simply move the .rbs file into the tools folder manually, as this often fails. 3d rad exporter plugin
When executing the export command (), the configuration panel settings dictate whether 3D Rad will read the file properly. Use the following baseline profile: Setting Parameter Recommended Configuration Coordinate System Right-Handed / Y-Up (or Z-Up depending on plugin version) Matches Blender's workspace to 3D Rad orientation Export Mode Binary or Text (Text is safer for debugging) Binary yields smaller file sizes; Text allows manual edits Export Animations Checked (Only if rigging exists) Exports keyframed bone movements Include Skin Weights Binds the mesh vertices to the bone structure Texture Path

Some versions of the plugin attempt to clean up "messy" geometry (like stray edges) that could cause physics glitches within the game engine. Usage within the SketchUp Workflow
