Texturing sweep profile tools

ZBrush Usage Questions
#1

EDIT: I reinitialized my model and it is working fine now. Oh well, I’ll take my blessings where I can :slight_smile:

I am having trouble texturing a sweep profile tool with a thickness of 10 using texturemaster.

When I paint on the ‘outside’ of the tool and pick, the painted area appears on the ‘inside’ of the tool and vise versa. The applied colour also goes on unevenly at the edges of the painted area, even with Fade on; this especially so on areas of high curvature.

I have tried turning on double sided options and flipping the normals but without any success.

Painting with back and front on works but paints both inside and outside surfaces (four in total) and is not always desirable.

Is there a procedure I should follow to be able to texture sweep profile tools?

Sure, it can be done. See above. :slight_smile:

The trick is to understand just how TextureMaster works. Basically, it will apply what you paint to all surfaces behind it that face toward you. In the case of something like the a SweepProfile with thickness, this means that the near exterior and far interior will be painted (since both face toward the camera). There’s the key. If you don’t want the far interior painted, then you have to hide that surface from ZBrush while you’re texturing the near exterior.

You could use masking to do this, but a far easier way is simply to move the vase so that it’s embedded halfway or slightly more into the clipping plane. Anything that falls behind the clipping plane won’t receive texture. I was able to do the vase above with four drops 90 degrees apart.

Of course, if you want to have some kind of design on the inside surface as well, then things get more complicated. But not impossible. Simply texture the model twice – once for the inside, and once for the outside. Then combine the two textures. The top half of the texture is the inside of the model. The bottom half is the outside. So when you combine them, remove the half of each that you don’t want. :slight_smile:

Thanks for the reply Aurick. Knowing the technical aspects will help for the future :slight_smile:

I didn’t explain myself well in my first post. What was happening was that I was painting the near exterior surface and when I picked, colour went only onto the interior (can’t remember if it was near or far); the near exterior wasn’t coloured at all. Odd :rolleyes:

(Although I have noticed that when masking sweep profile tools that a brush size bigger than a certain value will also cause the inside to be masked.)

But I got it working fine, even without masking.

As Tim Brooke Taylor of the Goodies used to say, “Don’t panic, I’m a teapot”. :slight_smile:
