sculpting seems slower than it should?

ZBrush Usage Questions
#1

before I get started my rig specs are

Windows 7 Professional 64 bit
Intel Core i7-4770k cpu @ 3.50 GHz
32 GB Ram
Geforce GTX 970x2

I’m running zbrush 64 bit. Fresh install on top of a fresh install of Windows. So I’m trying to work on a model at SubDiv 5. It has 332,225 active and total points and 5.308 million pixels. However the problem is, trying to sculpt on it at this subdiv is really slow where I have to leave my mouse in whatever location for a few seconds so the sculpt can catch up (I’m trying to make veins). I dunno, I feel like the sculpting should be relatively speedy still unless this is actually normal. I’ve run the multithreading optimizer as well. I also have zbrush installed on a 2 TB hard drive, dunno if that makes any difference. and it’s not full by any means, maybe 20% of the space is used.

Have you activated dynamic subdivision by mistake? (check Tool> Geometry >Dynamic Subdivision. Make sure it is not active.)

#3

Hello. I don’t believe it could be activated but I will double check. I literallly just imported the model through GoZ and increased it to sdiv 5 and noticed it was slow to sculpt. I will check when I get home from work though.

Just to clarify, are you familiar with the way a 5+ million poly mesh would typically perform on your system, or are you new to the program? A 5 million poly mesh is not much by zbrush standards, but it still might require smooth even strokes to keep from skipping.

Also, Lazy Mouse could be active for your current brush, which significantly slows down strokes in favor of making them smoother. Check the status of this in Stroke > Lazy Mouse, and toggle it on and off with the L key.

Ok I think I see what the problem was. When I import the model at base resolution and click Higher Res it activates dynamic subdiv. turning it off makes everything work great. Now I feel silly lol. Thank you for the help.

#6

Don’t feel silly. It’s a common problem. If a subtool has traditional subdivision levels, pressing the D/Shift-D keys will just cycle through the sub levels. If a mesh has no traditional subd levels, then pressing D to increase the resolution will instead toggle on Dynamic SubD to subdivide the object virtually. People with certain ways of working can find themselves accidentally switching on Dynamic SuBD, then further subdividing the tool which will leave DynaSub pegged on unless it’s manually deactivated.

First check the resolution if it is high then you can do it low and check it if it is not working then check the dynamic subdivision :smiley:
