I noticed, that while using Octane Color GUI Type there is mismatch between HSV and RGB display values. HSV = 0,0,50 ( 50% grey ) is displayed as 0,214 in RGB channels. Probably they are not linearized.
V value in HSV mode is wrong.
Bump channel is completely not visible using Box Projection... it is visible but it needs exactly 10 times more power to be visible as using UV projection.
