RAM Issues on projection - help appreciated!

Hello! I have a very dense mesh made from a while back. I finally was able to get a decent qRemesh result after lots of trial and error due to the nature of the model. The object is painstakingly polypainted so I am trying to get as much of that detail as possible into the new poseable mesh. I’ve been having a hard time for the last day and a half with crashes on trying to project up however. The model I am projecting to is 20 million polys (as it was a larger scaled object that was dynameshed when that feature came out). The reconstructed one can do just as well with less, but when I get it to around 14 million and try to project it, it always crashes. My system is running 32 gigs of RAM so I thought this should be doable.

I’ve tried quite a few things, including having a scene with nothing but those two objects. At one point, the projection did work without crashing (with the new 14 million and the old 20 million). That was the only time however and I haven’t been able to replicate it - wasn’t able to keep the result as I found there were some holes in the mesh from qRemsher.

My question is: Is there any known way I can increase the amount of RAM on my system Zbrush has access to? I tried raising the compat mem in preferences and pressing compact now, but no change (and I’m relatively un-clear as to how that works exactly). I believe it must just be at the threshold to crash Zbrush.

Any help is greatly appreciated. Thanks!

I was able to work around the issue by projecting isolated sections of each mesh then switching and projecting again - but would still love to know if there is any way to tweak/optimize the RAM use in Zbrush.

ZBrush is still a 32 bit app and can only use a maximum of 4 gigs RAM on a 64 bit OS. ZBrush 5 may possibly be 64 bit.

Thanks Zber2! I appreciate the reply. I hope subsequent versions will support x64 and more RAM - its one of the reasons I beefed this system up so much in that area. My bad on the timing, but at least its there to be used when they do.
