I'm a bit confused regarding displacement. I am embossing a logo onto a glass. I set up a file in Photoshop with a 50% grey background, and my embossed logo as 100% black with blurred edges. I save that as a 32bit file and put it in an image texture node connected to a displacement node and fed into the displacement slot of my Octane material.
I set the mid level at 0.5. I thought that would mean my black areas would be fully displaced, 50% grey areas would not change at all and white areas would be 'debossed'.
But it seems my grey areas are also being displaced a little. What am I doing wrong?
