When I click perspective on and off it doesn’t switch between perspective and ortho. Same problem on 2 PCs I’ve tried it on. If I create a new mesh it works fine. What did I do?!
Anyone? Is there perhaps a Zbrush version of 3dsmax’s reset xforms or snapshot abilities?
In the “Draw” palette, is your “Angle Of View” set to 50 (default)?
Thanks but yes it’s set to the default of 50. Sliding it up and down does nothing 
edit : Fixed. One of the subtools had infinite tiny hard to see dots (mesh) going off miles into the distance. So it was making the ztool too huge to do a perspective/ortho on. Masking/del geo wasn’t working so I deleted that subtool and remirrored the good half using subtools master (I’d use deformation mirror before which I’m sure caused the issue, it works sometimes but can screw up with certain complex geo).
