hi fellow blender-renderers
I have this highpoly, photoscanned model of a grilled hamburger with only a plain image texture.
The meat looks most delicious / realistic with a good amount of gloss that represents the hot grease. but the dark, almost black grill marks (where the meat got a little burned) don’t look realistic with gloss.
I’m pretty sure that I can remove the gloss from darker areas with the right material nodes setup but I don’t know how. Can someone hint me towards a node setup that would take the color output of the image texture node and tweak the data in a way that it can be plugged into the pricipled BSDF’s glossy input socket - so that it will apply higher glossy amount to lighter areas on the texture and less to the darker areas? I imagine a color ramp node within that node chain to tweak the threshold of glossy / non-glossy. It can be done, right?
or is there another way? I don’t want to select the dark areas by hand and apply a second material to them - too cumbersome and probably worse looking result.
Thanks for any hints! I imagine that for most more advanced blenderers this is pretty much child’s play but for me it’s somewhat advanced.
kind regards,
oyster
