Use of Polypaint From Texture? (Solved)

ZBrush Usage Questions
#1

Hi, I have a subtool that I’ve polypainted using a cavity mask to help define the edges of different coloured elements. This worked well and I’ve been able to create a texture map from my polypainting. However, the colour work I was able to do over my mask was predictably patchy in places (where the density of the mask varied), so I have taken it to Photoshop and cleaned it up. The result is much sharper, and I’ve applied the improved texture back to the model.

I would now like to be able to resume polypainting over my improved texture, but it is not baked back to the mesh. I’ve noticed the Polypaint From Texture option within the Polypaint tab, and it sounds as though it should do what I want, but it doesn’t seem to. Is there some step I’m missing, or is there another way to achieve what I’m trying to do? I imagine it must be possible to switch back and forth between ZBrush and Photoshop whilst creating textures.

Any suggestions very much appreciated.

You can use ZAppLink or Projection Master to paint directly onto the texture.

If you have the Extended version of either Photoshop CS4 or CS5, you could use GoZ, but I don’t see a path button for Photoshop in 4R2 Preferences > GoZ so I don’t know what’s going on there.

Polypaint from texture is what you want. You will have to make sure the MRGB button is pressed when you press the “polypaint from texture” button, and obviously the mesh has to be sufficiently high enough resolution to hold your intended detail. In order to see any polypainting, the “colorize” button in the polypaint menu must be pressed. And you will of course have to verify that the applied texture is deactivated to avoid any confusion.

Thanks guys - in fact the problem was due to my having left the masking in place (but turned off) :o it was just baking down the colour elements that were unmasked, and so looked exactly like the original patchy version.

It’s working pefectly now.
