Custom elemap crosshatch
Sumi-e brush (elemap not included)
The start sai program is quite handy, it can be found online .. somewhere. I ran into it a couple months ago when I was actively collecting brushes, but since I already had the program I didn’t bother bookmarking it.
(my version of) Sai only allows a max of 54 elemaps. I believe there’s a similar limit on blotmaps though I have not hit it yet. I think the Brushtex may be limited to 100 but I have likewise not hit it.
If you have brushes from multiple sources, consider taking the time to go through your collections to weed out duplicates. I hit my elemap limit when I was first assembling brushes, only to discover I had no less than 4 versions of multiple brushes, all under different names.
