Unable to render c4d gradient shader in Arnold

I can't render the c4d gradient material in Arnold. Does anyone knows the solution or knows how to recreate the similar result in Arnold?

Did you try the ramp shader?

Yes, i did. But when I choose circular type there, it doesnt render correctly.

The Cinema 4D gradient is set to '3D - Cylindrical' which is not supported by the ramp shader directly. I think the closest you can get is to set the Projection in the texture tag to Cylindrical and play with the scale and offset. Or use a uv_transform and uv_projection set to cylindrical in the shader network.

I don't see the Projection or uv_transform and uv_projection in the texture tag. Can you say, where is it exactly?

Projection parameter in the Texture Tag:

uv_transform and uv_projection shaders:

They are basically doing the same thing, so you either set the Projection in the texture tag or use the uv shaders in the network.
