It is blender 2.44. allwys the latest version. I can open the file in blender. but exporter is malfunction. what could be wrong? could there be a messed up mesh? i did use the ivy generator and after that the whole thing started to act up. Is it possible to fix the scene so it works propperly? or do I have to start over again? i didn't save in seperate files for each save i did. so i can't go back and do something about it.
