Today AvaStar released a new release. You can get it from your products page. I’m not sure what, if anything, is new or changed. I assume there are bug fixes. If you read the problems I had adding in the Slink 2.0.30 rig to the then current 2.0.46, you are aware of one problem.
The new version is 2.0.48. It updates easily. I disabled and removed 2.0.26, installed and enabled 2.0.48 (2RC10) without error.
Of first interest to me is whether I can update the Slink model I want to use. Slink updated their May 2016 to a May 2017 version. The 2017 version used AvaStar 2.0.30. The Slink people, AvaStar people, and I had trouble updating. Slink was gracious enough to update their files to 2.0.46.
With this new AvaStar version I tried updating the Slink 2.0.46 version to 2.0.48. At first, it seemed to have updated without a problem. I did have to close Blender and reopen to get the Outliner to update. Then I realized all the Slink meshes failed to parent to the rig in the update. So, I’ll have to move the Slink model and my things manually.
