combining 2 subtools where 1 is already textured ?!!

ZBrush Usage Questions
#1

Hi Guys,

I have sculpted a head for my first zbrush project. I didnt think when I started I would worry about the neck, but after completing the head decided that the model would benefit from it.

I have textured the head. If I merge the neck and head together by using the insert mesh method, will I have to re-texture the entire head+neck, or is there a way to retain the texture information for the head and be able to texture the neck seperately ?

Im kind of thinking this is not possible…

Any help is appreciated.

Cheers

Steve

Convert your texture to PolyPaint before you merge the model. Then you can continue PolyPainting after the merge, getting a perfect blend at the neck. Later you can split the model into multiple SubTools again to convert the PolyPaint back to separate textures for export.

Of course, you could also just use ZAppLink and blend the two parts together in Photoshop without merging them. Depending on your system’s capabilities and the model’s poly counts, this might be the better option.

Thanks aurick, the tex>col worked well. The only thing is now. When I drop my neck subtool to projection master (it has a base material of a skin shader). When I drop to the projection master, everything is fine. I can paint my textures on. When I pickup from the canvas…the texture kind of fades and looks like its faded in certain areas…

Any ideas why this is happening ?

Thanks

Steve

UPDATE: Its ok, I had fade turned on… :slight_smile:

Why are you using Projection Master? You can PolyPaint directly on the model without dropping it.

The reason being that I was using a technique to apply imported textures to the model. I go to projection master - select 3d plane - zadd to 0 - select a skin texture and alpha and then paint onto the model that way.

I havent tried this without dropping to canvas so wasnt sure if this would work.

I decided to use the insert mesh tool to blend all my subtools together in one mesh. I then used the texture to colour. Once I had finished texturing the entire model, I then selected col>tex and now zbrush is just sitting there using 25% of my quad core. Has been like this for 10 minutes now. Shoud it take this long ?

All my models within the scene have uvw coords…

How would that work, Aurick?.

Like Projection Master I thought ZAppLink only transfers color to the selected SubTool. So is it actually possible to transfer the photoshop data to two or more seperate subtools?

No. But if you have one SubTool that’s how you want it, why couldn’t you use ZAppLink to clone from there across the seam to the other part? ZAppLink will send all visible SubTools to Photoshop. But what you paint there will only apply to the selected SubTool.

Of course you could accomplish painting on both SubTools by a little trickery. Copy the editable Photoshop layer and create another temporary document with it. Then save the original Photoshop document and return to ZBrush. Switch SubTools without rotating or moving the model and go back to Photoshop. Now paste from the extra document into the new one and merge it with the editable layer. Return to ZBrush.
