Strange depth brush render bug

ZBrush Usage Questions
#1

Maybe someone could repeat :

  1. Select Depth brush.
  2. Select Modifiers DoubleSided.
  3. Select Drag Rect or Drag Dot Stroke.
  4. Select Alpha 0.
  5. Draw on canvas
  6. Press R
  7. Drag within Gyro to rotate

(Note render artifacts and also that the square alpha has unexpectedly formed an L shaped object)

  1. Select Alpha 27

(Note "L"ing remains)

  1. Enter move or scale modes

(move or scale a few times)

Although you haven’t posted a screen shot, I suspect that those artifacts are actually created by your video card. They should go away when you do a Best Render. Make sure that you have the most current drivers for your card (available from the manufacturer website).

Thanks Aurick, I remember you mentioning something about NVidia drivers previously; that seems likely to be the case here.

I think the “L” from alpha 0 may then be the more likely contender for the ‘bug’ list. The 3D forms that can be made using depth brush seem perfect in every other way.

#4

After installing the latest NVidia drivers the artifact problem continues. (i.e. with the square alpha : in terms of crashing the situation is worse than it was with the older drivers)

I will provide more information if necessary, I suppose I’d be surprised if the boffins over there don’t already already understand what’s going wrong inside out.
