I have run into a serious pair of problems in 4r7, both 32 and 64 bit. The 32-bit version will not dynamesh without producing a string of error messages (see attached) and then crashing to desktop, and the 64-bit will not save a tool without giving one and then crashing to desktop as well. Please assist. Thank you. ( I am submitting support ticket.)
You should probably post this in the 4r7 troubleshooting thread and keep it with the other issues, so the dev team can find them easier: http://www.zbrushcentral.com/showthread.php?191395-Questions-amp-Troubleshooting-for-ZBrush-4R7
I’m having the exact same problem, I’ve created a very detailed hi res sculpt and have had no troubles up until I got to about 134 million polygons and everytime I save now it crashes. I’ve spoken to a few people and so far I’m being told it could posibly be becuase I have a very new and fast graphics card I’m able to work in the software without a problem of but becuase the rest of my system is old when it tires to move that data to save it my processor and hard drive which are over 4-5 years old now and are lacking in power aren’t able to handle it and it crashes. Not sure if this is the problem yet but I’m going to upgrade in the next few days and hope it fixes the issue. If it does I’ll post again, might help you fix your issue too.
