Creating Alphas from masks issue.


I created a sketch that i wanted to import into zbrush so i could map it onto a plane and sculpt the detail. then grabdoc to use the alpha as a stamp.

What i did was create a plane in maya and UV map it. I lined up the drawing to the UV map of the plane in photoshop, then using GoZ i exported that plane to zbrush and imported the file with the drawing as a texture to use as a guide. Everything looks and works fine so far.

using the guide drawing, i mask it off by outlining the sketch and filling it in, but when i go to create the alpha out of the mask, all i get is either a full white or full black alpha.

I even tryed filling in with black and white and making a new texture from polypaint, but i get the same result; black or white file.

What am i doing wrong here?

I experimented with other models, same result.

When i press to create alpha from mask, i get a black or white file.

Create texture from polypaint, same result.

I was also wondering if it may be a hardware issue?

On my old computer this method seems to work fine, but i don't want to jump from one to another just to get a simple step done. If anyone has some helpful info, lease help.

alpha are black and white,
did you try tool>texture map>new from polypaint

the 3d plane is one way but have you looked under the DRAW menu on top?
draw>snap to Grid

That IS my major problem.

tool>texture>new from polypaint
tool>masking>create alpha
even multi-map exporter

all are not working as they should. Whenever i press the buttons to create the maps they come out as blank black or white files.

I went back to maya to check my UVs, fine.

Obviously my UVs are fine in zbrush if the texture with the drawing shows up on the model when i import it.

So im wondering what it is im doing wrong or if some of my settings are off?

And is there a way to check/edit UVS in zbrush?

Make Polymesh 3D.

The missing ingredient.

Or at least it made the tools finally work proper for me =)

Thanks for the input,
