DICOM are volume, but you normally visualize them, didn't edit neither texture them. So you need first to transform them in solid volumes. Not testing this in C4D so can't point out the exact workflow. If in importing DICOM C4D already make it editable no need for this. In any case to use it on a realtime rendered need to be exported in a supported format such as STL. Not sure about the 3D textures format.

Just to have an example let's say I want to import Ircadb 1.12 patient DICOM file, transform in solid one of the kidneys and next my goal will be to fill the volume with a 3D texture containing the tissue details such as in this example https://histologyguide.com/slideview/MH-143-kidney/16-slide-1.html?x=13531&y=24200&z=75.0 As alternative we can model every single tissue fiber and cell in 3d and apply a texture to them, but in any case I will need to find a way to replicate them so to fill the volume, transform in solids and apply a color to the solid. I think a texture approach can be more flexible and perform faster in our final goal that's realtime visualization.

Getting to work with the help of medical illustration professionals to create antomic models details starting from DICOM scans. I know in C4D is possible working with volumes, but to add internal details to the volume (i.e. the tissue) wanting to know if there is a way to texture not only the surface (so a 2D texture) but to texture the whole volume (a 3D texture). In this way cutting the volume you find always a detail, and not an empty shell with textures applied outside. Looking around in the forum I dind't see answers really pointing in this direction, so decided to ask for hints.
