Random Checker Color?

[peterparker242]

Hi,

i have a question. What do i need do to to get random colors on a checker-node?
eg. i have to do tiles for a bathroom. But the tiles have "slightly" diffrent colors. When i start using a grid i can choose two colors. How do i make a checker with more than two colors, like color1 varies from R0.1 to 0.18 and color2 varies from R0.15 to R0.20 for example. The color has to change for the whole color1 checker/tile, not like a fractal on a color.
What do i need to to, or do i need to do something totaly diffrent? Thanks for Your help.

Peter.

For MR or maya SW? (they require different approach the sw one being better but since mr cant read maya expression nodes you need to resort to a trick)

Here the diplacements are made with a simple noise function on each tiles value in mr

Offcourse you realy shoudl use a shader that acctualy filters.

Anyweay if you can sawer wich renderer you need it for i can push you tghe right way.

Hi,

thanks for Your fast reply! I would need an explanation for Maya SW. Ill try noise (but where put what?) If you could give me a walkthrough, that would be cool!!!

Thx, Peter.

Hi,
have a look at :

It explain how to use noise to create non-identical tiles ....

Hope it helps,

Hi,

cool tutorial Guyb, thx.
But thats a bit too complicated for me. I really only need something easy like.

Tiles order with checker:

black - white - black - white -
white - black - white - black -
black - white - black - white -

but i need to have something like:

medium grey - dark grey - light grey - black -
black - black - medium grey - light grey -
black - dark grey - black - medium grey

like shades of Black/white spread randomly over a checker.
Please help, Peter.

I'm afraid you'll have to go for something a bit complicated to do what you want to do as you'll have have to do "tricky" connections in your shader, as there's no straight forward shader to do that.

Nevertheless, I just though that you may be able to do something like that using not 1 but two checkers on top of each other (by connecting the second one in the "color balance/"color gain" value of the first one).

• first checker is just with black and 75% black 8x8 tiles.
• second checker scaled x 2 (in the 3Dtexture placement node), whith colors like 25% and 50% black.
  Try with different scale and colors, I don't have time myself to try to see the results, but it must be close to what you want ...

Good luck,
Guyb.

Thats by teh way exactly what teh link guy ti sent you is talking about except its the page just before that.

Note by the way this is actualy bad for 2 reasons, a expression nodes dont export to mr. It filtters nothing while it could easily do so.
