The new Quest:
extract Brightness values (HS-V) from RGB splatmap image as mask.
I created a dual splatmap image.
RGB for heights and slopes, and the coverage for foliage and others in the same 3 vectors but with diferent brightness values.
¿How to extract the brightness values as grayscale 0-255??
I tried de desaturate node , but has a problem. After remove the saturation, the values also changed. For example a vector R255(B100%) changes to R127(B50%)
¿what is the proper way to do??
I tried by multiply before by x3, because GRAY = (R+G+B)/3. = no luck.
Also saw a “tedious” node as 3PointLevels¿?
I need the mask from the RGB without using the ComponentMask nodes.
This is the splatmap for an island in the game.
RGBCMYK for heights but also diferent brightness inside for coverages.
