I need some information about:
- save preview images or assign new preview images via Python
- How can I stop "render preview image" process in preset library? In the settings there is a check box "Render scene" but I guess it is not related to this. After I create previews for my materials by "Create Preview" if my texture library is not active and I open this preset library everything seems black. So I have to activate or add texture path in the preferences. But I really need them to browse without make any modification. SO I need to fix their preview images. Is it possible to do that via Python?
