Title: UVW RANDOMIZER + NOISE
Post by: quatrosolo on 2022-11-14, 13:20:16

Is it possible to use uvw randomizer with C4d noise ?
I found a similar question for 3dsmax in the forums but nothing for c4d.

* What I am trying to achieve is combine a global noise pattern with an object specific one.


Best regards,

Hi there, care to share your results or material setup so far?

In the attached file you can see blocks of concrete with a universal noise pattern that continues between them.
I include another one with a white base material so you can see the noise more clearly.
What I am trying to achieve is add a separate noise pattern to each block individually.
UVW randomizer with a bitmap works, I was just wondering if I could do this with c4d noises as well since it provides more flexibility.
Thanks!

It's pretty straightforward - if the noise does not need UV coordinates, then UVW randomizer won't have any effect on it. In 3ds Max noise can be used in two modes - 2D and 3D. The former requires UV coordinates and can be used in conjunction with randomizer, the latter does not need UVs and randomizer does not work with it.

Unfortunate but makes sense.
Thanks for your time!

if you use the 2d (UV) noise in c4d noise, mode it should work.
