Using random color node to color correct texture ?

[Jukyan]

Hi,
the random color node is great in combination with gradient node,
but i would like to use it to change the hue of one texture (from one object in a cloner), so that only this textured objects has various shades of its texture.

I couldn't figure this out,
is that possible ??

Yeah that would be awesome. If you could expose somehow the Hue, Saturation, Gamma and Contrast values to the random node we could create some better randomisation. If you see in my parquet example its pretty straightforward what I'm trying to achieve random values for each plank, gamma hue etc.. I would go as far as suggest that a random rotation of the texture to flip etc would be nice if it could be implemented for example map the random node to rotate in 0 or 180 from the UVW project node. Maybe all that can't be done and are limited by the core, I don't know, Ahmet is the guy here, he can shed some light. You can test my simplified scene also and see what I mean.

Awesome, thanks!

I wouldn't have figured out the textures as multiple inputs for gradient node.
True that its a shame this node editor as so much limitation in the parameters access.
then why not implementing it for xpresso ?

Thanks.

Shame! Well thanks!

Haha!
Well Ahmet I thought you'll have a thicker skin by now.. We all know you do an amazing job.
Is that something that it could be Implemented easily (or not so easily) in the plugin, or does it depend on the core Octane, that's what I want to know.
Thanks for your great plugin anyways.

Hi all,

It's possible to do that with GaussianSpectrum. It's a little bit tricky but it works...

There is ports for the Color Correction node in the Standalone (Hue, Saturation,...) but they only accept various constant Float values (NOT "mapped" FloatTexture values). Right now it's not in the hands of Aoktar.

There is no useable ports for random colors in the Transform or Projection nodes in the Standalone too. Then Aoktar can't create nodes that doesn't exist in the Octane SDK. But indeed it could be very usefull to be able to randomize UVs transformations in instances.

Here my little and fast done sample. It's only one solution, there is another ways to do that but GaussianSpectrum is a good starting point:

Thanks;) I'm very sensitive to what i do.
Node editor is highly based on Octane nodes. But it's not anything more than working from mat manager. It's just a wrapper for your material editing. No extra storage not a xpresso. Just another shape of mat manager with extra capabilities.
Anyway it's possible to work with any parameter linkings. As i said it's just a monitor to node connections. Just will not display else of materials/textures like connections to another type parameters. But they will work and editable from another editors.

Also, the Tab node in Xpresso provides access to those parameters.

Thanx guys,

I see the use of the GaussianSpectrum is brilliant, never used it before nor would I ever think to use it like that..! If you can think of other ways also, please do share.
