Here is my import process :- ) {maybe it could be streamlined even futher?}
1)Open library
2)Click on material in Material editor
3)Click '+' in CMPP, voila, material added ! I can instantly use it on different 3dsMax file opened, without any restart, since the files are located on disk.
4)Make larger instance of material editor preview (quality 12), screenshot it, save in PS and on the disk.
5)Click image import. Now I have nice thumbnail as well, and it took no time at all.
+ points:
It saves the materials as regular libraries, you can still send them to someone who doesn't use plugin. He will simply import it in Material browser, which is slow, laggy, ugly and with super small thumbnails that need to be rendered realtime (more lag).
I can save them with information in text (usually UVW size, project used, notes to team mates how to use it best).
Looks very good. My OCD side is really happy if something is nice and tidy and looks modern. The other free plugins look like shit. They might work just as good but...that's big no for me.
There are some discounts now on it on website.
