hello,
Blender 2.5 is alpha now you can donwload binaries
hereIf you want to test it here is the alpha0000 of export script.
All functionnality are not supported (i didn't find how to set environnement mapping flag for example).
This script will have two option:
Export Scene: will create one .tri file with all scene objects scaled and rotated if needed.
Export Elements: Will export each mesh in it's own file (name based on mesh name). This allow to create rapidly elements meshes directly from one blender file. Hope i can save image too.
Give feedback, i'll try to incorporate them if i can.
Have a nice day.
Ouille.
P.S.: Put this script in .blender/scripts/io/ directory
