Subsurface shaders taking in nearby colors?

Hi! I made a post the other day about applying skin shaders to primitives and got an answer, so I was messing around and ran into something new! Say I have a purple primitive using the purple gummy shader. Next, but a second nearby and set it to another color. The white primative will render purple if too close to the purple object.

How do you fix this?

    Are you rendering with UE in GI Bounce mode?

    Also, try setting one primitive to one group id, and the other prim to another group id (not sure if that matters with separate objects, but hey). The setting is in the surface options.

    I'm using UE, what's GI Bounce mode? Edit: No I'm using soft shadows, not bounce mode.

    GI Bounce will cause color bleed to simulate radiosity.

    Do you have the same subsurface group on the surfaces of both objects (the 'Group ID' in AoA SS shader)? If so setting them to different numbers on the two objects should stop the colour bleed.
