Colour Change Problem

This may be a newbie issue - if so, apologies, and thanks for any advice.

Following closely the polypainting tutorial on ZClassroom, I loaded a Polysphere from the default Zscript menu. This defaults to red wax as a material/colour.

When I try changing the colour or material pallette, the whole mesh changes colour/material, regardless of what mrgb or rgb settings are selected, and WITHOUT painting on the mesh, and WITHOUT selecting ‘fill object’ on the colour menu - the whole thing just changes, as soon as I select a colour. Makes it kinda tough to select a paint colour…

If I then try to paint a line onto the mesh, I get a colour (say green) with (say) a red wax border, ontop of the already green sphere … Wierd.

The interesting part is that on the tool menu (docked on the right) the tool preview shows what I would expect - a red wax sphere mesh with green line painting on it.

And if I go to 2.5 D, and draw the tool onto the canvas, what I see is a red wax sphere with a green paint line on it, not a wholly green sphere as is shown on the main edit window.

I guess its possible there some option or setting I’ve misunderstood, but this looks very much to me like a bug on the edit preview render.

The same issue seems to exist with changing materials, by setting the M setting instead of RGB…

The issue is demonstrated in the screenshot below:

Hi wbrook,

A mesh will take on the selected color if the Tool:Texture:Colorize button is switched off. If the button is off by default then it will switch on automatically when starting polypainting but sometimes there’s a display lag on screen which causes the effect you describe - rotating the model slightly will fix it. Alternatively, just switch on Tool:Texture:Colorize before starting painting.

Materials work slightly differently in that a mesh in Edit mode will always take on the selected (‘Active’) material until it has been filled with a base material. If you wish to paint with materials as well as color:

  1. Select a base color and material for your mesh.

  2. Switch on the Mrgb button in the Draw palette.

  3. Press the Fill Object button in the Color palette.

You will then be able to paint colors and materials as you wish.

Welcome to ZBC and happy ZBrushing. :slight_smile:

HTH,

Thanks Marcus - I guess they missed that bit out of the tutorial !

I guess its a case of ‘RTFM’ (read the flippin’ manual) !!

Cheers,

Bill.
