Painting with textures, keeping my UVs?

ZBrush Usage Questions
#1

Hiya,

I’ve imported an obj with a pre-made UV Map. I loaded a texture of rusty metal and it is instantly mapped on the object using the UV Map… This much is expected. What I would like to do is paint this texture in various locations using the drag rect stroker. But it doesn’t work unless I first click “Disable UVs.” Doing that lets me paint this texture anywhere I want on the model in colourize mode, but my UVs are obliterated. Is there a way to get into this painting mode without trashing my UVs? Thanks!

there’s not, but all you need to do is go back down to the lowest level and reimport the uvs when you’re all done painting.

Import UVs? How do I do that? Re-import the obj?

#4

Ok thanks nredit… I’ve figured it out with storing morph targets, etc. I hope ZBrush 4 can disable UVs without eradicating them, because that is one weird workflow!

Hi, Ive just tried out and replicate your problems. Its not really not working, the problem with it lie with the display.
When you painted with the texture on, it got baked into the pixols,
But it wasn`t shown because it got overridden by the mapped texture.

But it shouldn`t be that much of a hassle, since the only time you need UV is when you finished painting and wanted to bake it into the texture.
In which case, have a UVed - back up model prepared would let you import the UV at anytime when you are ready…

I dont think Ive seen anyone post this issue on ZBrush4 wishlist yet, try it.

I`ve never tried Morph target method before.
You can import your UV by import OBJ file back at the same division level.
Or, if your LowRes mesh changed after sculpting -
Export as an OBJ at the resolution that you want
UV it in another app
Export as an OBJ
and import back in ZBrush at the same Division level.

Well the bizarro workflow was a success… I was able to get my hands all rusty. :slight_smile:

Where do I post wishes for ZB4?

It`s been going on for 2 yrs since ZBrush 3 was out.

Thanks Zenneth… I posted 4 requests.

Carm3d,

Some users have found the Polypainting plugin >>> HERE <<< to be useful when “painting” with various texture maps on a polypainted model. The plugin simply automates a lot of the steps you’d be doing by hand anyway.

Looking at it now, the plugin could be refined a bit more… (for example having it remember to automatically reload the output texture map each time you press step 4, then step five, to copy over the new polypainting to the output map instead of having the user remember to do it.)

Still, you might find it useful for what you’re doing.

Thanks Sven, I downloaded it.

I’m done with polypainting for this project. Here is the result:
