I have just upgraded from HF2 to HF4Pro and am crushing on what this software can do currently and where it is going!
I'm having an embarrassing difficulty, however. I am wanting to make an HUD graphic interface design using (among other things) 3 circular rings of slightly different sizes rotating around a single point in 3D space. I am finding it simple placing two masks on a plane, one slightly smaller than the other to make a perfect ring. What I have not managed to do is to figure out how to perfectly center the mask(s) on the plane so that I can parent it to a point. Even making a square composition (400x400 in this case) and attempting to nudge it into center has been only crudely accurate and the rotating around the point is still off center and "wobbly".
Additionally, I saw in the "Creating Animated Masks" tutorial on Youtube that Shift is used to constrain a mask to be a perfect square or circle, and that Alt allows you to pull a mask from its center. This tutorial was for HF3. Is the Alt option still available in 4?
I'm sure there is an easy solution for aligning that I am too dense to see right now. Thank you in advance for any and all help!
