This is driving me nuts and seemingly nobody has had this problem.
I’m trying to sculpt these teeth and both the automask by polygroup and topological mask the moment i turn them on simply don’t let me sculpt anything.
Instead, the geometry i try to sculpt just entirely moves in a seemingly random direction. Here’s a picture. that’s the direction the tooth moved when i moved my cursor from the tooth to where it is.
Does ANYBODY have any idea what’s going on?
Try setting your Draw Size to something greater than 1.
how strange, it did it still on more than one draw size when i was trying ot trouble shoot it initially, i rebooted zbrush, now it ONLY does it on one draw size.
Before it would work on any size for a few minutes as long as i kept rebooting zbrush, not it seems to be working with anything BUT one.
So is this a glitch? Why would the brush size have this effect? For all i know it might stop working entirely again but it seems to be working.
This is of course annoying because i sorta need a small brush for part of what i’m doing, but whatever, i’ll make due. Thanks for the reply!
You can always use masking or mesh visibility isntead of auto-masking. Shift+Ctrl+click to show a polygroup, Shift+Ctrl+click the background to show everything.
I’ve no idea as to why the problem happens.
Well that’s what i ended up having to do and it’s annoying to have to do all those steps to isolate one tooth and mask it, reverse the mask then sculpt.
But i’ve NEVER had an issue with working with a 1 size brush.
I"m now sculpting another part and suddenly if i use a 1 draw size brush, it starts to warp and flatten the entire subtool. It’s utterly bizarre. It wasn’t doing it the day before yesterday and it just started.
for how long zbrush has been around, i’m getting really sick of encountering all these bugs.
Here’s a macro that will help you mask everything except the polygroup under the cursor. Save the file to the ZBrush 4R7\ZStartup\Macros\Misc\ folder and then press Macro>Reload All Macros or restart ZBrush. There should then be a new button called “Mask Group” in the Macro>Macros>Misc sub-palette. You need to assign a hotkey to the button for the macro to work.
To use the macro simply place the cursor over the polygroup you want to work with and press the hotkey. Everything except that polygroup will be masked.
I’ll let the development team know about the problem with a Draw Size of 1. For me this only happens when Auto Masking>Mask By Polygroup is on.
