From 2.6 to 2.4

Support Animation and Rigging

Hi
I need export my animated model to md2 format.
I found that only blender-2.4* can import/export this format.
But i can’t correctly open my scene in old blender-2.49b - animation is lost![TABLE=“class: gt-baf-table”]

[/TABLE]
How to open my animation in blender-2.49b?

I highly doubt you will be able to perfectly recover your animation in blender 2.49 from 2.6… mainly because of time with changes to the core of the blender file itself.

that being said can you use md3 file format? there is a md3 exporter for blender 2.6 (md3 is quake model 3 instead of quake model 2)
