noooooooo, damn you pixologic for aquiring a sculpting program that actually had viewport navigation nailed down perfectly and replacing it with zbrush awkwardness :( lol
Pixologic just released a new video in the zbrush classroom featuring the zsphere 2 workflow. http://www.pixologic.com/zclassroom/homeroom/ Looks awesome imo! Cant wait.
I am not sure how much this will actually help you though I recommend looking at all the features Pixologic is implementing in zbrush... http://www.zbrushcentral.com/showthread.php?164835-FiberMesh-Preview
You could try an annotation software like annotatepro for example. I admit it would be nice if pixologic included one directly in the next version of zbrush though. That would be quite useful!
I have had this happen before on certain meshes and it sounds like a bug. I'd suggest submitting a ticket with pixologic. https://support.pixologic.com/Tickets/Submit
I dunno man, part of me says that if this means Pixologic will finally update GoZ to work with the latest versions of Maya that this can only be a good thing.
Like a lot of others. The way layers worked before was tons better. But they modified to introduce the animation features, that are useless for almost everybody. Damn you, Pixologic.
