Thin Film & Dispersion Shader
What is the difference between this Thin Film Shader and the built-in Thin Film feature in Blender?
This Thin Film shader is a standalone Thin Film node that outputs just the raw color data from the thin film spectrum, giving the user much more felxibility and control over the brightness, saturation and mapping of the thin film colors.
Does Thin Film work in Eevee?
Yes - The thin film shader is basically just a color ramp mapping real-world thin film data onto the fresnel falloff of the surface. This works in Eevee no problem.
Does glass dispersion work in Eevee?
No - The glass dispersion feature only works in Cycles Render.
