ZBrush 3.x: graphic card issues on macbookpro

ZBrush Usage Questions
#1

Hi,
I noticed this problem on my macbook pro 2.2 intel duo. When I sculpt in normal edit (not quick 3D edit) all I get are these holes on the mesh; different DSmooth setting doesn’t change anything. It’s only a graphic problem because if I refresh the rendering (moving the tool ie) I see the modified mesh; it’s just the realtime render that seems broken. I just downloaded version 3.2 but the problem is stil there… In quick 3D mode all works well.
This is the graphic card installed (standard): GeForce 8600M GT

Cheers

Are you using the stock drivers, or have you updated to the most current drivers from the nVidia website?

#3

Stock drivers. The machine is up to date but only with standard apple software update.

#4

First off, update to 3.2.

Second, get the most current drivers from nVidia.

Hi Aurick,
thank you for your answer. As I said on my first post the problem is present in version 3.2 too. Then, on mac laptop I can’t update video driver other than Apple software update… Nvidia doesn’t support drivers download for Apple’s Mobile cards.

#6

Another possibility: Are you using a Wacom tablet? If so, update to the most current Wacom drivers. Some people have reported just this sort of issue with older drivers.

#7

Yes, it could be.
I check tis and I’ll let you know.
Thanx

#8

Upgraded wacom to the last driver but the problem is still there…

#9

either 10.5.8 didn’t solve the problem. Did anyone with a 2007 macbook pro recreate that?

#10

Because 3.5 for Mac is going to be real (I think :wink: ) I ask to investigate better on this issue. It seems that snow leopard doesn’t help but now I’m sure it is a software problem, not hardware. I tried the same thing with the same hardware (my MacBook Pro) on windowsXP with bootcamp (I have a 3.1 windows temporary crossgrade version) and there everything works right… So I have no idea where is the bug, probably is the video card driver, but please check if you can.
Cheers

Same problem on win XP 32bits
Nvidia 8800gt

#12

So is not a MacOS related problem but it rather seems a Nvidia issue… It’s strange that using the same video card in win XP with bootcamp the problem disappear…

#13

Is awesome that nobody else report this problem i just tested another graphic card nvidia 8500gt with the most new drivers and the problem still there

Yes it’s strange. Ok it is not a big problem because in quick3D mode you can sculpt quite well but it’s strange that we are the only two people experiencing this problem :slight_smile:
