Hi
I’ve just spent four hours re-topologiesing a model. Suddenly I found I was having trouble moving some of the nodes. Then suddenly I couldn’t move any of the nodes. I saved the subtool and restarted ZBrush. Now I can’t even add any more topology, let alone move any of the nodes.
Can anyone shed some light please?
Hey there,
if the points are “locked”, that means they are actually masked. Just clear your mask (ctrl + shift + a) and you should be ok.
After reloading your retopop Mesh, you need to go to Tool/Topology and click on Edit Topology again.
Hope that helps.
Thanks for getting back so promptly dsoellbuster. I have frantically been hitting cmd/shift/a all night with no result.
After receiving your suggestion I finally took a look at my Mac keyboard and realized my mistake. ctrl/shift/a works a treat.
Thanks. I had an awful feeling I was going to have to start from scratch.
Thanks again, you’re a life saver.
P.S - why doesn’t ctrl drag on canvas clear the mask?
You should be able to open up the Masking palette and control your mask from there via pressing buttons for Clear, Mask All and Inverse, using that menu to control those masking functions if needed during retopo in zbrush.
Edit, yeah I just checked that on some live retopologizing and indeed that’s how it works. Last note there, Ctrl and clicking while dragging outside of the model and onto the canvas does indeed clear the mask for me when topology editing is “live” so I’m not sure why that’s not working for you. However, I’m not a mac so I’ll stop here heh as that may be the problem, I have no clue about macs.
Yep Ctrl + click + drag does work, somehow i just prefere ctrl + shift + a, as that gives me the impression, that i’ve made sure i’ve cleared the mask 
I also use it during retopo, when all your points disappear because you’ve selected a point by ctrl clicking on it. Moving the mesh on the canvas would bring them back as well, but i’ve developed a habit of using the shortcut … 2 flies with one swatter so to speak.
