ZBrush mask by subtool intersection

Rabbid_Cheeze

If you have two subtools overlapping one another is there a way to make one apply a mask at the areas where they intersect? Sort of like a boolean operation but instead of subtracting/adding geometry it subtracts/adds masks.

A way to transfer masks between two objects with similar shapes would be useful too.

Bump.

I dont know about intersection between separate tools. A very tight AO sounds like one possible solution to look into. If you could merge them into one tool with separate polygroups it may or may not help things as well.

For similar shapes, you could try turning the mask into grayscale polypaint data and projecting it onto the new one.

I would also love to get a solution for this...Splitting meshes/subtools where they intersect is what I've been searching for

Bump. Any new discoveries?

I'v messed with this for a while and haven't come up with anything. Wish I did. Would be really useful.

EDIT:

I found this on Zbrush Central posted by Marcus. Not really a 1 click solution but better than nothing.

1. Turn on Ghost transparency. The subtool you want to mask should be selected and the subtool you want to do the masking should be visible.
2. Select the ZProject brush. Make sure just RGB is turned on.
3. Paint over the subtool. The one you want masked will become black wherever it is covered by the subtool.
4. Press Tool>Masking>Mask By Intensity (under Mask By Color).
5. Turn off Tool>PolyPaint>Colorize to see the mask.

Nice one @nyx702

Thanks for a good fix

Can anyone confirm if this method still works, or suggest other methods, I just tried and it wasn't working and I need it for something I'm working on. Even with zmodeler brush, it painted everything black
