Out of memory

[Anonymous]

Hi, 

Im new to Mudbox, so I hope this is a simple fix. I'm trying to load in a mesh from 3ds max to mudbox (using the "send to mudbox" option), but am running into an issue; Mudbox reports "Out of memory" when I try to do nearly anything with the mesh. Undo is the worst, but even just a grab will cause issues.

Currently there are no lods/levels, and the mesh is only 13,048 polygons, but mudbox is eating well over 13gb of memory (this seemed to climb from 6gb  I messed/clicked and got that error, but as of writing this has leveled off to 13gb). 

Win10

I5 4690k

24gb ram

gtx 1080

log and dxdiag attached.

What is the fix for this? Is this an issue because the mesh came from Max?

Thanks for the help

Edit: This happens as well when I export the file from Max as an fbx and import it to Mudbox, except I lose all my nice quads and it draws all the triangles. When trying to make a new scene when its in this state, Mudbox keeps the memory its gathered, but crashes soon after.

Hi there,

Sorry you are running into this! Would you be able to share the file with us? If it's under 10 MB, you can email it to me at jill.ramsay@autodesk.com. Otherwise I can send you a link where you can put it. Also which version of Max and of Mudbox are you using?

Thanks,

Jill

Hi Jill,

I'll get the file sent off to you so you can look at it, but playing around with it I believe it may have something to do with the size/scale of the file. When I scale it smaller before importing to mudbox the issue is much less likely to happen. I have not extensively tested it yet however.

Hi Matthew, 

Definitely something very strange going on with this mesh - I don't get the out of memory error (I have 32 GB), but the grab brush moves the entire mesh, and if I do freeze transformations and then use the grab brush again, I can crash Mudbox reliably. Thanks for sharing your file - I will let you know if we discover a workaround.

Jill,

Sure thing, thanks for taking a look. Like I said before, I can avoid most
issues if I shrink the mesh down very small before taking it to Mudbox, so
its not terminal, just a little annoying to work with brush sizes 0.01 to
0.5.
