viewport problem?

ZBrush Usage Questions
#1

hello. i’m new to ZBrush. i’m actually running the trial version of ZBrush 4 to see how i like the app. i’ve noticed a viewport issue with a particular tool and i was wondering if anyone here has expierienced this same problem. when i bring the tool “PolyMesh3D” (the star shape) out into the viewport, and i start to move and rotate it, the polygon leaves a trail of little bits and pieces of the the tool. i’ve included an image of my viewport so you can see the issue. if i begin to add resolution to the geometry, the problem goes away. and this only happens with this particular tool.

anyone know what’s wrong here? thanks for looking :slight_smile:

Hi galactic,
I have the same problems with zbrush in my machine as well .The artifacts were clearly indicating a graphic card problem .So replaced the graphic card .Still no solution :(.
I think there could be two ways to deal this issue,
1:A Mac OS X :snow leopard problem not compatible with zbrush
2:A GRAPHIC CARD design Issue with ATI.

I have similar issue with GUI rendering in Maya view-port (Maya 2011).

I got this issue while the polygon is yet to be divided ,when i divide the artifacts don’t appear while moving in 3D view-port.

If u have found a solution ,please do mail me .

My system config:
8core ,2.4GHz ,6GB ram ,ATI Radeon HD 5770.

Thanks .

I have the same issue as well. It seems it may be some sort of problem with zbrush and rendering very low polygon objects. Try increasing the amount of subdivisions and see if that resolves this issue.

hi Perfectblue,

Yea it could be issues with zbrush with rendering low polygons .As u did experience ,when i subdivide ,the artifacts don’t appear.
Well ,i could not completely rule out the graphic card issue since ,i am getting issues with Apple’s own software products like itunes ,where pixelated boxes appear when i switch playlist :(.Well i am still talking to apple customer care regarding that issue.Hope we get a solution soon.

If the issue in Zbrush ,well we got a bug to be reported and to be fixed !

if u find a solution plz do share with us and do mail me ,
