File Size and Ram Limit

ZBrush Usage Questions
#1

Hi,

Ive been working on a project that demands as much detail as possible on the mesh, but Ive been struggling to work on some assets. Those assets are intended for games, so some details needs to be sculpted.

The problem is that its getting really hard work and crashing quite often during the end phase of each asset. Usually it gets heavy on assets that reach 200 millions the whole scene, with the heavier subtools around 25 millions and one layer in some cases and the medium level subtools around 15 millions. Im aware of the file size limitation being around 4.1 GB, so I believe that it`s around the max polycount I can work for the entire scene. The problem is the laggy performance, 99% of memory usage and constant crashing.

So if the Pixologic team could help me trying to figure out if there is a solution for this or the only option would be to break the asset in more subtools than I already break, I`d be very grateful.

Hardware upgrade is an option, but since its hard to find ZB benchmarks comparing different rigs, I dont know what kind of upgrade could really help.

This is the company PC rig:

i7 6700
32 GB Ram DDR3-2133(1066 MHZ)
SSD HD

Thanks \o

Are you using the 64bit version? That should solve the ram issues…

Yeah, Im using. The problem with this project is that my team is responsible just for the High poly and base texture phase(polypaint), if I was doing the whole asset I could use different solutions to add details and solve some of these problems during the texture phase, but thats not the case.

I forgot to say that Im working on a Cintiq, so its using a 1600x1200 resolution.
