Avastar anim format

Avastar anim format

The internal serialised animation format that SL and OpenSim use is usually given the extension “.anim” and so has become known as the anim format.  The more common path of importing animations, through BVH files, actually just translates the BVH format to the internal format when you upload an animation.  Some details of the internal format can be found here.

Avastar supports many of the features of the anim format including per-bone priorities, animating attachment points, and encoding the loop parameters, ease in and out, hand pose and emote directly  in the animation file.


Uploading the anim File

The import of .anim files is as easy as the import of .bvh files.

* Go to Build -> Upload -> Animations.
* Select the animations you want to upload. You can select several but they have to have the extension “.anim” or “.bvh”.

You will be charged L$10 per animation so be sure of your choice. They will show up in your animations folder after a few seconds.

For .anim animations all the animation parameters such a priority and looping are set in Blender at export time.

    I have uploaded both BVH and ANIM files to SL and I have discovered that they are not the same.

    If I upload a BVH file to SL and then try to export it again so I can play with it in BVHacker, no problem.

    If I upload an ANIM file to SL and then try to export it again, my viewer crashes.

    I have to surmise that uploading an ANIM is NOT the same as uploading a BVH file to SL. Either something extra is added or something is left out (missing) when uploading the ANIM file to SL.

    Any clue why this happens and is there a workaround for it?

    It should be noted that the official SL Viewer version 3.3.1 and above now have native support for uploading .anim files.
