I just downloaded the Blender CVS for Linux and when I go to export my model to VRML 2.0 (in the export menu) I get an error saying version mismatch: this script was written to work with v2.32 and you have v2.31. It lets me try to export anyways and when I do, the program crashes and exits.
That’s exactly where the Test Builds forum on blender.org has been created for. Instead of posting the problem here on elysiun, you should’ve posted this on blender.org and it might have been solved for 2.32. Now you can be sure it isn’t solved.
