CHANEL - LE VERNIS Metalic collection

[elliasp]

Because of Keyshot material limitations, I had to render this image 2 times :

- 1 with glass IOR  low to allow some parts of transparency

- 1 with glass IOR very high to have glass reflections

That mean a lot of post production on photoshop (and I don't even speak about metalic flakes...).

Cant' wait for K3, I hope material editing will be enhanced enough for my expectations.

not so fond of the black parts at the bottom of the bottles ... other than that, perfect render !

[slyer]

Very good work !!!
It's true that we can spend lot of time on post production but I think it's a necessary step to fully complete a render.

Nice image ... What is the "limitation" with glass now?

[elliasp]

Yes Thomas, I know, I'm never happy 

Let me show you what I'm talking about :

On glass, solid glass and liquid materials, we should have a level of reclection not linked to IOR :

IOR should only be the glass refraction, separated from an other parameter of reflection, it will allow us to be more accurate about materials...

tres sympa tes explications, merci.

Ton rendu est vraiment reussi.

How high was the ray bounces on the 1st render ?

[elliasp]

It was until it change something in glass material : level 16...

[PhilippeV8]

The trick with the ray bounce is to put it on very high .. like 32 or so, then change it to say 20 and check if anything changes in your realtime render window .. if nothing changes, further reduce till you find the lowes possible setting that gives you equal result as when you'd set it to .. say 100.

Did you use this trick ?

I have a feeling you could get ridd of the black bottle botoms this way ..
