I uploaded a new version of the M15 export script for Blender. You don't need to rename texture references of TGA textures anymore. That was 1 line more code. Phew, to much work

Get it here http://community.thinbasic.com/index.php?topic=593.0
and copy it into the location where all your export scripts a located. Also download Petr's viewer and copy it over to the same location. This way you can view an exported model without a thinBasic script right away.
