Okay thank you for your answer

Good weekend !

I managed to find a solution for the contrast but for example for the Cycles parameter it's the same, it doesn't work.
user data control mat.c4d

yes I tried using just the node value, it work. But then I can't use User data to control the Contrast parameter of the noise for example? And I have a question: I managed to control the Hue parameter of a Golaem HSL with user data. I don't understand the difference between the Maxon Noise's Contrast parameter and the Goleam HSL's Hue parameter. In terms of values, the 2 go from -1 to 1.

Hi ! I created a User Data parameter ranging from -1 to 1. In the material, I created a User Data Scalar to retrieve the value of my parameter. When I connect it to the HUE port of a Golaem HSL it works, but if I connect it to the Contrast port of a Maxon Noise it doesn't work and I get the error “This port needs a constant value”. How can I fix this?

Thank you

Thanks! I've managed to bake the texture with the redshift baking system, it works. It's pity you can't see the appearance of redshift materials directly in the viewport without enabling IPR. I remember creating orbs with animated noise and ramps on them, and I had to render several times to adjust the speed of the noise. Good day

Ok thanks, and can i precalculated the ramp? or maybe the solution is to bake the texture.

Hi Dr sassi
Is it possible to see the texture without using the IPR? The animation doesn't play in real time when the IPR is activated.

I made an eye texture with Ramp and Layer. In the 3D viewport, the eye is completely black. Is it possible to preview my texture in the viewport? I'd like to animate the size of my iris with UV, but I can't see it as everything is black.

Thanks you i will ask in the developer forum

Hi I have a lego project on Cinema4D with a lot of identical object. I would like replace all identicals objets by intances. Can select objets by the points number? for exemple i would like to select all objects with 152 points. Is it possible?

Thanks !
