Hi the library browsing of 3d models has slowed down significantly in the last few versions of the software. Thumbnails would generate instantly in old versions now there is a noticeable lag while going through folders and scrolling down. I still don’t understand the thumbnail cache feature as it doesn’t seem to do anything. It will be fast for the last folder visited and then it goes slow like the directory falls out of cache or memory or something.. how to fix or is it a bug..

Plugin version: 3.40.34
3ds Max version: 2026
Renderer: Corona13

Also, one customer had a problem on Windows 10 without updates and Dropbox.
So, please check, if you use the required version of MySQL (if you use it) and have installed Windows 11 with all updates.
