Hey Athanasios,

thanks so much for this tutorial - I’m working on a project right now where this technique is helping us build a scene that’s super easy to control. The only problem is, we’re rendering in redshift and I have the hardest time figuring out how to translate the 3D World space ramp that you’re controlling via xpresso (to fade in the inside cracks) to a redshift material. In case you work with redshift - do you have any idea how to translate that to a redshift material?

Thanks so much!!!

Hi conrad.oswald,

I have send Thanassis a message, if there is anything useful to share, I’m certain he will do so. Edit, he is gathering information at the moment. /edit.

If you can’t utilize any Gradient in that way, I think it should be possible to set this up in Redshift, you might render this gradient animation as clip and apply it as a texture.

All the best

According to a redshift Guru, a Spherical Gradient doesn’t exist like in C4D. A workaround could be to use Vertex maps (File link attached) but this won’t work with Generated objects. It only works with mesh objects.

Here’s a Video by Liam Clisham about RS and Vertex maps:

On the other hand, and again it’s a long shot, does Redshift have a way to control the opacity using Lights? Something like the C4D Lumas shader.
If that’s possible, you can imitate the effect using a point light with a falloff (gradience).

At this point I can’t think of anything else, but if I do, I’ll make sure to post it”

Thanks a lot for your help guys!!!
Adrian from Redshift helped me with a setup that replicates exactly your technique with vectors: https://www.redshift3d.com/forums/viewthread/18945/

Nice, that the Redshift forum’s thread has progressed, conrad.oswald.
Thanks for the heads-up. I hope that will help others to use Redshift for those projects.

Enjoy your project
