The Blender proggy has settings for when a person imports obj files, and again when a person exports them. If not set correctly, they can make a seemingly good obj file impossible to work with in S3D. My COVID mush-brain cannot remember who it was that pointed me to correct settings... gap? vickers03? kapuhy? someonelse?...
- Anyway, that is the main problem (usually) when working with Blender-ized files.
