Hi all,
I'm coming here as I've tried several things over the course of the day including using Booleans / modeling this in. Trying a decal. Only using bump which looks naff.
Literally, all I'm trying to do is deboss this bird logo into the cylinder
Any takers as to what I'm doing wrong?
Thanks in advance

Hi,
Try to set min level to 0 and max level to - 0.3 or whatever depth that you need.

Exact same result. This is one of those times where something that should take 2 mins takes all day :') hahaha

Invert the image colors and also invert the min displacement level ( minus 0.3 ).
-
Same exact outcome, just inverting an invert
-
linear displacement normally requires a + and - value where 50% grey = 0%.
So in your case 0% displacement is grey (use a soild colour layer) and the dove bitmap is -X (use the image on top multiplied) with and equivalent +X value

Nope, you must be doing something incorrectly since it works on my side.
@davetwo is right, the correct workflow is to use a different map than for the bump and use a 50% gray color where the geometry should not move. But Corona allow you to set min/max level ( some render engine only have one value = the total height of the displacement ) and you can take advantage of this. So -3/0 with a black and white map or -3/+3 with a gray map is really just the same thing.
