Hi Sapphire9,
Thank you very much for your file.
I have not used your file here; only the core part was recreated.
I had to replace the Tube with an Extrude set-up to get the UVs I needed. (I’m not a big fan of the Triplanar node for high-end renderings.) With that, while all Volume modes are off, I rendered the Voronoi Fracture with the main camera. This camera can’t be changed after that!
This rendered clip can then be used to camera project it onto the Volume result. Redshift (as you certainly know) has a specific camera-map node for that.
As this is a question that addresses Cinema 4D renderer and can it be applied to RedShift 3D, I explored it here in this forum. (Typically, I try not to interfere with the Redshift 3D forum, as long as I’m not advised otherwise).
Since Redshift3D targets (more or less) real-time performance, I exported the mesh into an Alembic file, and the camera mapped it onto this. To leave it in the Volume settings had some downsides anyway.
I hope that helps.
