Continued thread

A fair question is, does it matter? It depends. For some looks you're better off with a dielectric film (it renders faster). But when it does matter, there's no denying the absorption is required for the right look.

Example: copper with a layer of CuO, where the layer doesn't have absorption. Compare with the image in the first post of this thread (repeated here), where realistic absorption is added.

Now I need a real Dev to fix my baby C++ code😅

#blender3d #b3d #thinfilminterference

Quite pleased: I added native #thinfilminterference in an absorbing layer on top of a conductor to #blender3d. I went through the math of hal.science/hal-01518344/docum, and added terms dealing with absorption in the film. Slightly trickier than I thought, but it works. The 5.0 alpha branch dealing with dielectrics was great as a starting point!

The render shows the result with nodes on the left and the native implementation on the right. If you look carefully there's a slight color shift.
