Study Circles material-variability ... Yes, but with a twist

[mvgulik]

Kinda funny that those Study Circles in the image show some material-variability differences.
But in game the build has no preview. And the one I build uses an other color too.

Guess the dev's forgot something again, or are experimenting with some obscure new test feature.
Strongly suspect "the hand of Jorb" was involved.
