I don’t know if I’ve done something to this ztool, but for some reason the Std brush will not affect it whatsoever.
The brush works fine on any other tool, so I’m guessing it has to do with the tool? It’s not the masking either, I cleared mask when I tried.
Anyone ever encounter this?
Have you made sure that your tool settings(add/sub) are something other than “0” ?
yeah, i tweaked around the buttons, checked the mask, tried the brush on another ztool and it works, come back to this one, and it stops working. 
It even works on other subtools within this ztool, quite the interesting bug if you ask me…
sounds like you have a mask on that object
tool>masking>clear
No i don’t, I cleared it quite a few times to make sure too…
