Alpha Problem

ZBrush Usage Questions
#1

Hi, may be really obvious but i’ve made an alpha 512x512, im dragrect’ it and it goes on the model fine vertically but when it comes to a smaller part of the hair the alpha won’t go horizontal (trying to go in the direction of the hair flow), just gets very pixelated.

The alpha is fine horizontally when its really big but i need it on a quite small area. Ive tried changing the alpha res.

This particular part of the har is lower geometry than the rest, could be part of the problem.

Any help is greatly appreiciated.
Thanks

I think you are probably right - it’s the lower geometry that means you aren’t getting the detail. Try subdividing the model to see if it makes any difference.
