dear all,
sorry for my maybe obvious question, but the more i work with the new physical materials,
the more i start to lack a direct control on the reflection intensity (other than lowering or raising the ior).
mostly to lower the reflections a bit as i see in in real world products i need to recreate.
to all my understanding the IOR is MAINLY defining the falloff/fresnel curve of an material, not only the intensity of the reflection, so metals have a very different fall off curve than water which again is different to glass and so on ( as easy seen on
https://refractiveindex.info/ ).
but atm i see no other way to tune the reflection intensity in the physical material, other than changing (raising or lowering ) the IOR value.
- do i oversee something important?
- is this really physical correct?
- aren't there materials in reality who have a certain fall of curve , like glass, but different reflection intensities? (lower than pure ior value would indicate p.e.)
- would it maybe be needed, to have an intensity slider i % or a value (ideally with texture slot) for the reflection, at least to lower it at least for artistic reasons i think this is important.
as example: seeing at real world glass products i think also reflection can very different for different products, and i assume they all have an ior of 1.5-1.6, not much lower.
so i feel a physical material still needs some way to set the reflection intensity independent from the fall off curve (ior)
what does the corona team or other users think on that?
maybe a "level" setting like in Volume tab,
or amount with a texture slot, like in refraction tab of the new physical mat would do it?
cheers
Stefan
p.s.: just to make clear i love the new Physical material,and the intention behind it. all i post is only trying to help to improve it:)
