I’ve added full support for Caligari trueSpace files to my Radiosity Import Export Suite. So now you can export radiosity solutions from Blender to trueSpace.
Run the import script, then middle-click on a file with a .cob, .scn, or .radio extension.
Run the export script, then enter a file name with a .cob or .radio extension. If you middle-click on a file, it will be overwritten without warning.
Isn’t the automatic file format detection wonderful?
.radio - import and export
.cob - import and export
*.scn - import only
Download the suite here (in the Python Scripts section).
