Color picker grabbing wrong color

ZBrush Usage Questions
#1

Hello,
So I’ve been living with this issue long enough and finally decided to turn to the forums for help. But my color picker is not picking up the right color. It seems to be a few shades darker then the intended color. Does anybody know why this is happening or any work arounds for it? Thanks for the help. I attached an image to show you what I am getting.

What’s your OS and ZBrush version? You may have accidentally painted color or material while sculpting. What you see may not be what you get depending on render settings and type of render.

Hello,
Thanks for the reply. OS is Windows 7 Professional and ZBrush version is 4R5. I gave him a base material of toy plastic and as far as I can tell haven’t done anything else that would cause this behavious. But my coworker sitting across from me doesn’t have this problem which swings it back around to user error potentially. Could it be picking up shading information or something? I sorta don’t think it is. Is it a 2.5D thing? I’m kinda at a loss for troubleshooting this. Thanks for the help.

Most everyone else has upgraded to ZB4R6 P2. Are you working in 2.5 D? http://docs.pixologic.com/user-guide/materials-lights-rendering/materials/

Hi, well I got an email into our software purchaser to please send me the Zbrush upgrade link so hopefully I can get that taken care of. I don’t think I’m working in 2.5D (although it was my understanding that ZBrush’s ‘3d’ is really 2.5D which is what allows it to handle so many polygons so wouldn’t that mean we are always working in 2.5d?, anyway, I digress). Short answer, is I shouldn’t be working in 2.5D. And the color picker has been around in the last several versions of ZBrush so unless they made some enhancement to it in R6 im not sure what the version would have to do with it picking colors accurately? Any thoughts on that?

I don’t think I’m doing anything particularly unique here to get that result. Its essentially if you were to start with a sphere, make it a polymesh, apply a material, apply a particular color of paint of your choosing, then try to select the color you just painted with the color picker, and then paint some more on the sphere but its a different color other than the one you originally painted (a couple shades darker then the intended color). That is essentially what is happening here.

A 3d object in Edit mode is a fully 3d object that you are working on in real time. You are actually assigning color on a polygon by polygon basis when polypainting.

I can’t recreate this issue. Things to pay attention to:


  • *Which modifiers are active for the brush (RGB, MRGB, ZADD, etc). If MRGB is active you are painting with material as well as color, which will impact the appearance.
  • *Make sure any Masking has been cleared from the object. Manually clear it, even if not visible.
  • *What is the RGB intensity slider set to? Are you painting with 100% of a color, or some % ?
  • *Certain stroke types, like the sprays, have a color variance effect that can be adjusted in the stroke properties.
  • *Does this happen with every tool, or just a specific one?

It’s always best to work with the most up to date version of Zbrush, unless you have a specific reason not to.

Thanks for the replies. Frustrating because now I cannot recreate it either.

Although, Doug, I think that may be whats going on here. Im going to try to do the fix in that link I just dont want to lose the texture I have painted so far and my model doesnt have any UV’s yet. So I’m going to go about saving this stuff out and then trying the fix. Thanks again! I’ll update how it worked.

Oh, Can you UV a Dynamesh? I may need to finish my scultpting before I attempt this.

For what you have shown in your screen grab, I’d just start over with a ZSphere armature and then adaptive skin. Dynamesh is good for some things but, I probably wouldn’t be using it in this instance.

Thanks… Yeah its been awhile since I’ve touched ZBrush. Current job has me all over the place so I am trying to reacquaint with this current project we’re working on. I’ve missed it a lot and there is so much new stuff now I am back to feeling like a noob :frowning: :small_orange_diamond:sigh:small_orange_diamond:

There are several ways of picking colors and there are two types: ‘shaded’ and ‘unshaded’. Shaded is the actual color that you see on screen, including shadow and material effects; unshaded is the pure color.

If you use the hotkey ‘C’ to pick a color then that will be unshaded - the pure color.

If you click+drag from a color selector to pick a color then that will also be unshaded, unless you hold Alt (after starting to drag) in which case the color will be shaded.

HTH,

Never ceases to amaze me how I can learn new little things about Zbrush even after ten years of use.
