Simple stamp brush.
Custom portal brush, stamp type.
I created it to look like a point/checkpoint item like in racing minigames.
It can also be used as a portal/void frame, or whatever you can think of.
Can use any color. It has transparency.

Can be extra by using 2 layers.
01. has base color (examples are green and orange)
02. Has second color. I recoment making it smaller, and "Screen" layer mode (yellow and red).

Is a simple portal, and I looks good when you add a little extra (airbrush tool)

This is how I used it. double color + transformation + masking layer + airbrush.

I would love to see how you use it! Tag me on it, I'm Gashicalmy everywhere.
