Cant go past level six subdivision level

#1

Hi,

I am trying to detail my base mesh in mudbox, it will get up to level 6 on this mesh but no higher before running out of memory . I cant get enough detail at that level. Its a human face so I am trying to add skin texture and wrinkles. My base mesh is only like 2000 poly’s. When I try subdividing mudboxes base head mesh it goes up to level 7 before running out of memory. Does anyone have a solution please.

Here is my systemspecs

why in the world do you need 30 million polygons for a head? i think you can’t expect that with only 2gb of ram…mudbox alone needs over 2gb when handling such a dense mesh.

jepp you need more ram… i recommend a min of 8gig…

I see also that you’re on 32bit. You’ll need a 64bit OS to access more than 3gig (if you enable the 3gig switch). I can get up to about 10million on a 4gig 32bit system.

Perhaps instead of sculpting the skin detail you could try using a bump map.

thanks for the comments. I am new to mudbox so if there is a more efficient way to get more detail at lower levels please tell me.I know I have a outdated computer, but I have to make do with what I have until I can a upgrade.

Try painting on Normal Maps (or create one, just like you would with diffuse). With normals you can simulate fake detail on low polygon surfaces, much like bump only better.

the work around is hide the polygons you dont need for faster performance.
