Ok, I’ll edit my post to avoid confusion.
Light, and Shadow from IFS Illusions are done. I get the naming convention now. But, Bright and Dark throws me off in terms of naming convention. So, I renamed Light to Illumination, and Shadow to Shade. Brighten will be renamed to Lighten, and Dark will be renamed to Darken. Not sure about the naming convention here.
By the way, I’m down to six compatible blending modes from IMBLEND. I could emulate mesh to a degree with the aid of conditions, modulus operation, but I don’t feel it’s worth the pain doing that.
