Blender exporter (v70) to json three.js skinning animations

Question

It took me a few weeks to master the Blender to json skinning export process, but the final result was working great prior three.js exporter v70.

I had to rebuild my dev machine and I installed Blender three.js exporter v70.

Today, I am doing a simple update to a blender file with skinning animations that was working fine prior the update and I am not able to get multiple animations to export as before.

I have tested Blender exporter with a simple object and animations and I get the same results.

Exporter output:

Any idea what should I be doing to get multiple skinning animations working again?

Answer 1

Until r71 is released it is advised to use the dev version. Multiple animations have been restored plus numerous optimizations, features, and bug fixes have been addressed (specifically to animation exports).
