Problem with cylindrical map applied to a ring of clones

[shawn]

Hi:

I have a feeling I'm missing some simple setting, but I can't get my IPR to match what I'm seeing in Open GL.

I have a ring of long capsules (clones along a circle spline), and I want to map a ramp around those clones so each capsule is (essentially) its own color taken from a sliver of the ramp. My ramp is set to u, and the material is being mapped to the group of clones using cylindrical mapping. It looks correct in Open GL:

But when rendered in the IPR the ramp is being wrapped around each individual clone, making each capsule identical:

Again, I'm probably missing something simple. When I do the same thing using the standard C4D materials and renderer the ramp renders as I want (as in the Open GL).

I've attached a scene file.

Thank you.

Mappings in the Texture tag has this special mode when assigned to a Cloner or a Null which is not supported in Arnold. The objects are exported and shaded individually.

You can use a gradient shader effector to control the ramp, as described here:

Or use the shader effector directly in the shader network.
