Where do I load an opacity map in ZBrush

So I have imported some hair polygon strips into zbrush and there are also corresponding color texture map and an opacity map. how can I import the opacity into zbrush and use it along with the color map?


Hello Zolly,

ZBrush doesn’t use Opacity maps. However, if you activate the Transparent texture option, ZBrush will read any 100% black area in the image as transparent.


So these are the two maps i would like to affect my mesh, do I need to combine them in some way?

So I did try to combine the two above images into one so that the background would be black hence transparent. (did this in Gimp) Here is the result when the texture is applied to the hair polygons subtool. Any thing some one can recommend to get an improved result?
