We have released a new version of the BlenderKit add-on(both for 2.79 and 2.8).
There are several new features, but mainly stability fixes in 2.8 version:
- Thumbnail previews now respect image aspect ratio.
- Asset preview scales down when it doesn't fit in your 3d view.
- Ratings UI was moved under the asset bar - it's now more visible and hopefully bug free.
- We did quite a lot of work to strip down the size of our addon.
- New Fluid preview object helped a lot to keept he file size down, and also looks better!
- Asset preview text was reduced, to keep things more readable.
