I was doing some retopo work using an appended Zsphere in a tool. Suddenly Zbrush 4 crashed and right after restarting it, I tried to load my retopo tool back again, but then Zbrush just crashes again.
This happens every time now, with any of the six tools I’ve got saved from that session? The files are about 90mb each, but that shouldn’t be too much?
Is it possible to load/restore these tools in some way?
Hope someone can help! Thanks.

I heard if you select a ZSphere first in your document before you load in your retopo it won’t crash. Hope that works!
YES! That works, thanks a million!

If you Save your Ztool without the edit topo button selected it shud load fine for future reference and reopening, I had the exact issue ur having but on a tiny file of abt 14mb so i cudn’t understand how zbrush cudnt handle it… lol
Cheers ‘benmillion’ worked like a charm for me
