Yeah just noticed. Fed fresnel float into a normal input, passing it through a group untouched, and out came a gray fresnel, meaning it was converted to three channels. I just feel it’s wasting something when all I’m dealing with is a float. Example of a normal linear interpolation as a float group; makes up a node group and consists of 4 math nods, compared to a color mixer which does the same thing as a single node (but expected to calculate same thing on all three channels):
Which one is most beneficial wrt rendering speed? I btw hate using the color mixer with custom value inputs as I can’t limit their input same way as I can with values exposed to a group interface, and letting them stay as colors makes them unreadable until you click on the color making maths difficult to debug.
