Brush Opacity Issue
I can't seem to get the brush opacity to work on a custom brush I'm trying to make. The brush and Layer opacity are both 100%, the modes are normal, there's no transfer effect applied or anything, and I've tried both resetting the tool and deleting Photoshop's preference files. Nothing has worked so far. It also keeps switching between brush types so I'm unable to use certain brushes with the pencil tool even though I usually prefer it, and the hardness option is completely grayed out.
