random tiling

[elesar]

3d max has a shder that create tiles with random colores
I tested many things and nobs in maya to create this effect
but I could not.
dose any body know how we can create this texture?
is ther any MR shader that create random multi color tiles?

[kjaft]

tiles white random colores
can you please describe this a little bit more specific?

I think this is what you are looking for.

oh!
excuse me kjaft
it was a mistake in spelling
white = with !!!!!!!!!!!!:D:o
I want a procedural texture that generate colors randomly.
if we can particularly map each color we can handel many natural (and artificial)phenomenons.
this is so handy in architectural rendering (& misc)



thanks peengoh!
im going to read it

[elesar]

ok i read that
it was grate
but we can not map each color separatly in 2d noise
think about different things
some thing like agranite texture that placed randomly in a building surface and each tile has a different color and a little
different granite texture

Interesting!

Well, as a matter a fact you can, just read well, you can map anything to the noise, and as many tiles as you want, all you have to do is map the tile (color) you want.

very cool technique, old, but great. however, mental ray isnt supporting something along the way. so far i havent singled it out yet..

;) thanks
ok Idont know is it exactly what I want or not
But Im going to play with it:cool:


I like to have control on each tile some thing like my shders in renderman that helped me to map the color , texture , bump , aim and other Properties SEPARATELY PER TILE.
its realy handy

[ironhalo]

has anyone got the exact setup to work in mental ray? it looks like the expression used to truncate the colors in the noise procedural isnt supported in mental ray.

[elesar]

wonderful igi
that's the point
it is exactly what I want
thank you :cool:

About that discrete tiling tutorial, the problem is indeed with the expression, which I think isn't supported by mr. I had this very same doubt once. Try using Pixero's JS_Expression shader instead:

Also take a look at Pixero's JS_Mosaic:

Advices by Floze and Pixero himself.

i ended up baking out the procedural, and that worked. i should probably look into pixero's shaders too. more control versus the baked image.
