How to create a texture (for export) after you polypainted the model allready?

ZBrush Usage Questions
#1

I have an issue with one of my models.
I just started to play around with zbrush not too long ago and thus i forgot to Make an UV, then make a texture from polypaint right at the beginning, but i believe it should be possible to do that later.

So the steps i took:

Loaded the tool.
Subtool Master - Merge (cause if i don’t Daz Studio ignores the sublayers and i get an incomplete model)
UV-Maps -> UV Tiles
Texture Map -> New from Polypaint

And then the program freezes and never shows any reaction again.

The goal: take my finished model, make a texture and export it for Daz Studio without having to repaint everything. (I could do a “New Texture” and it works just fine, but then the paint is of course gone.
Please help and thanks in Advance

Don’t use UV Tile. That won’t work with Polypaint to Texture. PUV Tiles, AUV Tiles or GUV Tiles will work fine or create UVs using UV Master.

Thanks for the answer, but I can only chose PUV Tiles if i don’t merge it. After I merge, it writes
"Optimal UV mapping can not be achieved with the current UV Map Size and UV Map Border values.

Increase UV Map Size or decrease UV Map Border and try again"
But if i blindly change those values, it messes up.

If i go for GUV or AUV Tiles, that works, but after I make the new texture, that texture just looks like a big chunk of error.
(several broken up blocks of random color that isn’t even on the model)

Regarding the UV Master i have no clue how to get an exported Texture out of it…guess it’s back to searching for tutorials on that.

I really love the way i can work on models with this program, but the interface and the part where it gets to export stuff outside of it, really gets me raging sometimes

If your merged model has several million polygons then you will need quite a large texture map to capture all your polypaint detail. As a rough guide, a 1024x1024 map will be OK for about 600,000 polys, 2048x2048 will be good for about 3million polys and 4096x4096 will be OK for about 12 million polys. (But all these values depend on the UV mapping method and how efficient it is.)

It’s best to use a texture map size of powers of two: 1024, 2048, 4096, 8192. If you change the UV mapping then you will have to press the Tool>Texture Map>New From Polypaint button again to get a new texture map. Before you do this you will see a blocky mess on your model if you have already created a texture map.

Whichever method you use for creating the UVs (including UV master) the way you export the map is always the same:

  1. Press the Tool>Texture Map>Clone Txtr. This puts a copy in the main Texture palette.
  2. Select the texture in the Texture palette and press Texture>Export

However, if you are using GoZ there should be no need to export the map separately provided the Tool>Texture Map>Texture On switch is on and the Tool>Texture Map>Texture Map thumbnail displays the texture.

HTH,

Thanks again, have to try it out and see what happens
