Smooth Brush causing noise.

ZBrush Usage Questions
#1

Hi all,

Since installing the 3.1 update I have been having continuous problems with pushing shift to alternate to the smooth brush. What is happening is when I press shift to smooth my model, the brush is creating noise instead of smoothing.

I have not set any options on the smooth brush, no curve alterations, no cavity masking or any of those options are turned on. There is no alpha being loaded into the smooth brush. When I switch to the smooth brush manually it works as expected. Only when I press shift does it have this problem. I’ve held shift and clicked the smooth brush, and I can see in my UI that pressing shift is switching to smooth and not to some other brush with an alpha.

Please see the attached image to understand what I’m seeing. When I start ZBrush fresh I dont have this problem. It seems that it only happens after using a special brush like clay, or ram, etc… and it is totally random. When it will smooth or make noise. As far as I know I am the only person in the universe who has seen this, as I’ve shown it to some co-workers and none of them can figure out whats going on.

Thanks,
-Pete

Make sure you are on ZAdd not ZSub when using Shift to initiate smotth brush. With ZSub smooth brush changes into some weird noise brush… which could be useful for some things… that we are yet to discover :slight_smile:

Please try the following:

  1. Select the Smooth brush (don’t use Shift). Then set a lower Z Intensity (like 50) and choose a soft alpha (like Alpha 01).

  2. Return to your other brushes and use Shift like normal to smooth.

  3. If necessary, also try adjusting the smoothing curve at the bottom of the Brush palette. You could also try setting the Brush>Auto Smooth Strength to 2.

hi guys, thank you for the replies!

As Darkside mentioned it is indeed the fact that the brush is set to SUB instead of ADD. I discovered this earlier today and have since learned to use the Alt key to subtract, and always keep my brush set to ADD. I guess this is a new feature, or maybe theres some way I never noticed it before?

Thanks again for taking the time to reply. :+1:
