Gaia has a post out today (5/13 – Wednesday) announcing a new release of AvaStar 1.5.6. See: Avastar-1.5 is Out.
There is an update tool in AvaStar Blender. I was thinking it is in the release I have, 1.4.5. But, I don’t see it. Seems it only arrived with version 1.4.8. If you have 1.4.8 the last part of the video shows how to use it. Otherwise, you will have to download 1.5 and manually update AvaStar as I did.
There are a number of small fixes in this release. The list of them is in the announcement. But, the most interesting ones are discussed in the video.
