Custom OBJ exporter is written. Tests are starting today. If all goes right, I'll release a quick fix specifically for 4.10 to allow users to use VWD in 4.10 awaiting repairs from DAZ. It's not a perfect solution because this custom exporter will have to be reviewed a every new Studio release for changes in the internal model. I'd rather use Daz exporter when it works. This export problem is also an issue for other uses of Studio (export to blender or octane for instance) and I think Daz will eventually solve it. Stay tuned for more news
