Thanks to users who provided good feedback and sample Max files to debug from I’ve managed to nail a couple of annoying bugs in my 3DS Max SMD exporter plugin.

The first bug was incorrect error warnings about a mesh not having Sub/Muli-Object material when using a non-English version of 3DS Max. Thanks to Cherubim Entia for reporting that bug and testing the fix. The second bug was the exporter crashing when a rig contained a lot of mirrored parent bone/objects reported by “ifO” over at Mapcore who provided me with a good description and a Max file to debug from. The fix for this bug should also fix the crash when exporting an animation backwards.

Thanks again to those of you who have reported bugs and sorry I haven’t been able to jump on the problem as quickly as I liked. Hope the updated plug-in fixes most of the current issues.
