a way around right to render for vehicle .dff files
Before importing the model into Blender, I used RWAnalyze to replace all "Right to Render" extensions in the .dff file with empty extensions. After that, I imported the cleaned model into Blender, made my edits, and re-exported it.
The final exported .dff works perfectly fine in-game, with no crashes or rendering issues. This proves that "Right to Render" is not required for vehicle models, as long as the rest of the structure (geometry, dummies, materials) is intact.
This method can be really useful for custom vehicle exporting, and it would be great to have an option for this in vehicle export tools—skipping or stripping the Right to Render extension automatically.

DragonFF adds the "Right to Render" extension only when exporting a DFF with SkinPLG (model with armature). If I'm not mistaken, there is no SkinPLG in vehicles, so the "Right to Render" extension should not be added. Were you able to export vehicle with this extension?
No, I was never able to get the "Right to Render" extension to export with vehicles since it’s not supported in your code. However, I can get cars to work fine without the "Right to Render" on the vehicle DFF.
