Hi guys

Im debug cosine values in matrerial and all values which it gives me are different from regular w7 calculator in both grad/rad modes.
Cosine of 0.2:
In material = 0.3090
Calculator (rad) = 0.98
Calculator (degree) = 0.99

Why cosine in UE gives me that values?

Figured it out: cosine have default period of 1. In should be set to 2Pi (6.28). :rolleyes:
