MC uses flat for leashes and only leashes

I see. The issue arises because shadows can’t be applied to the rope—only traditional sky exposure affects it (for example, in a cave the rope darkens as expected). As a result, it appears lit as if it were receiving direct sunlight, and this effect is further intensified because the camera’s exposure adjusts to the dark environment. It’s unfixable and a consequence of how lighting works in MakeUp.

Sorry.
