Have made a simple backfacing based setup for filtering the albedo color with vains mask from albedo is based of simple inverting and contrast increase depending on the albedo ofc.
with 0.9 absorption fac
For comparison without absorption filtering.
Awesome. A question, why invert the color of the texture?
Thanks.Because this leaf albedo has very bright veins, I inverted the albedo so that the veins become darker, and then used the result as an absorption multiplier.
For other albedo maps, the method you use to create the absorption map is entirely up to you.
Here the preview from the albdeo to vein mask
This absorption map gets mulitiplyed by the absorption color to get the filtering mask
In the last color mix the amount between white (1,1,1) and the filter result gets interpolated as mix fac how strong the original albedo gets filtered,thats it
