Hi,

Is there any way I can group multiple objects (like spheres and cylinders)
as a texture?

I basically want a graphene sheet, like so:

And use that a texture on a cylinder or a plane.

Thanks for your time,
Tarun

There's the object pigment pattern, described at section 3.4.11.23 Object
Pattern in the doc, yet it doesn't allow for texturing.

You might need to use image_pattern instead, by first making an orthographic
rendering of the object. See section 3.4.11.20 Image Pattern. Then you can
apply any texturing for the parts dependant on the gray value. For wrapping
to a cylinder just use map_type 1, as per the usual image_map items.
