Jax- Yes, the problem only shows up after saving(and used) as a brush, and then only the right side does the trans/opaque issue (which issue is dependant upon the the type of shading I including in the drawing to begin with. The sample just shows two types I have played with. Using "shade lines" (1 px wide black lines in various angles/places) gives either pyramid stairs or solid black upon insertion, using blur goes solid black, shadint the whole brush face sometimes goes all transparent) I am just lost here. (and going bald at this rate!)
Edit: Ive been following tuts by RobA and Gidde and Ironmetal250 as I work on this.
