I have a folder with some b&w images that I want to use as brushes textures while sculpting.
Is there a way to automatically load these images as brush textures, or do I have to do it one by one?
After you have it installed, simply click on File > Import > Brush Set.
You have to choose a folder (don't pick any images, just the folder) and the addon will import all the images in that folder and set them up as brush textures. (It would be a good idea to make a separate folder with only the images you want to import)
It's as simple as that.
