blend2panda.py

Pipeline
1

I quickly threw together script that exports meshes from blender through .x format.

Tested on windows, should work on linux i guess. In case you have blender on non-standard path - you should it put on PATH or edit script so it can find blender.

Use:
copy script to panda3d-1.8.0\bin\blend2panda.py
run: python blend2panda.py mesh.blend mesh.(x|egg|bam) [-d] [-f]
-d - mesh is dynamic (export animations)
-f - export full animations (not only key frames)

You probably will want to use -d -f always for animated meshes.
As you can see you also can export to x, egg and bam formats.

My test mesh came out sort of messed up, i dont know if its fault of exporter or what. Dont feel like testing any more today. Im leaving script for you kids to play with :slight_smile:
