Title: How to tweak reflection and refraction using physical material?
Post by: TeoRossi93 on 2021-04-15, 12:07:39

Hey guys!

I'm trying to figure out how to tweak parameters of refractive physical material.
How can I decrease reflection strength?
How can I change refraction/reflection glossiness independently?

thanks guys

By lowering IOR value.

Not possible, at least for now.

Well modifiyng IOR will affect even refraction behaviour.
I will stick to the legacy material for refractive stuff.

Yeah, the physical material is not made with cheating in mind. Luckily we have legacy material for that :]

Cheating is such a strong work. I like custom better. You can customize the legacy material to your liking. Much nicer sounding, no?  Haha

I didn't want it to sound deprecating, sorry for that. Lets phrase it that way - new physical material is not well suited for taking artistic liberties.

LOL ya still does not make it a good situation. I want the Dev's to commit to never removing the "old" Corona material.

I never liked it being called "legacy", calling it "basic" or something like that would be more reassuring :)

Can't disagree with that.

Cheating physical standards, bending light... a dream every human has :)

Bending light is not witchcraft, you just need to eat a lot to gain proper weight.
I've been getting ready for this experiment for a while ...

Sure, there's no magic, but witchcraft nonetheless.
And as a matter of fact, truly dark one.
Light bent is only one which passes by...

event horizon
