So in Z4 I can not polypaint onto more than one subtool at a time!
I can not paint directly paint onto texture maps.
Can someone tell me I’m wrong
Thanks
You can paint into maps directly (kind of) with Projection Master. However, it is bugged and the fade is not working in Z4. As to not being able to paint across subtools, no you can’t. You can only have one subtool active at a time and you can only paint on the active subtool, hence no painting across subtools. Hopefully we’ll see a fix for Projection Master, but in the mean time might want to look at the Mari Beta for your texture painting needs. I don’t think true texture based painting is going to ever be a part of Zbrush (famous last words 
.)
It is a big bug to me that polypaint can’t work on more than on subtool. I don’t know if it’s technically impossible for Pixo but it would greatly ease the use of zbrush. C4D can paint accross maps but Zbrush deals with brushes and applies paint in a much better way.
After the large leaps forward with Z4 maybe the Zgod will consider thiese improvements for Z5. and soon…
It’s not a bug, in that it’s not doing anything it wasn’t designed to do. It’s a limitation. Zbrush was not originally intended to be a texture painter. It was a 2.5D app, a paint program for sure, but not necessarily a texture painter. What it’s become is primarily a sculpting program, but it is not everything to all people and has never claimed to be. Unless there’s a big change in direction, I wouldn’t look to see big changes to UV/Texture painting toolset. It’s likely going to be polypainting being burnt to UV painting at the end. As I said, you might want to look into Mari from the Foundry if texture painting what you need. It looks like a very robust tool that would do exactly what you want. Also, there’s tools like xNormal that will allow you to project your painting from a high density/ugly mesh with ZBrush UVs to a nice topolgy, low res mesh, independent of topology. That tool is free and worth a look as well. But it’s a bad trap to get into, expecting Pixologic to solve your texture painting problems.
Of course bug is to mean annoyance, not as in bad programming. Whatever Zbrush started as it’s direction has moved beyond sculpting and encompasses surface texture hense lightbox. Zbrush is great for what it does but this product can be developed further by allowing users to work on more than one subtool at a time with polypaint. Sadly Mari is Linux only and I’m not going there. Thanks anyway.
Actually, Mari Windows is in beta at this very moment. I’ve been watching it’s progress closely, as that though I like Linux, it’s not ready for prime time with what I do. So don’t discount it yet. If you’re on the Mac though, then yes, you’re stuck. Though I wouldn’t be surprised to see an OS X port, if there was market for it for the Foundry folks.
Missed the Windows Beta - looks nice.
