Hey guys.

So how do i offset my UV's/texture randomly on a bunch of instances? C4D here.

Thanks!

Hi MantasKava,
you need to use a gradient node in complex mode with the random color node as input, look at this example with the same texture and different uv transform values:

Hey Bepeg4d,

Thank you alot for your effort.
It ALMOST works, the only problem is (and you can see it in my attached screenshot) that all of those textures gets blended on top of each other, and it shouldn't be this way. You can see it better if you input different textures into gradient node and lick them to diffuse channel.

Is there a way to overcome this?

I believe you need to change Interpolation to Constant.

Hi everyone! I´m using the 2020 version and It doesn´t work for me, I guess I'm doing something wrong but I don't know what :roll:

Hi,
please note that Random Color node works only for Render Instance/Multi Instance cloners, and the multi-texture Gradient cannot work with Texture Displacement, you need Vertex Displacement instead:

Thank you for the quick answer, but I still can't get it to work, not displacement at all... :?

Hi,
please check that the Displacement nodes connected to the Vertex Displacement Mixer are both set to Vertex Displacement, instead of Texture Displacement.
