My tests

[Jiri.Matys]

Jiri, Wow, the bathroom images are my favorites. Did you use the the Vray lens effects or add in post?
Anyway, I always struggle with tiny spaces but your cameras are really nicely positioned. Brute Force GI?
Okay, I'll stop pestering

VRay lens effects and maybe corona lens effects too from CIE, not sure now. But I used some abberation in post too so effects may look little bit different.
Sure, its Brute force + Light Cache, I think best way now in VRay.

And about camera position, I sometimes use little trick - put camera behind wall so camera take almost whole room at some good focal lenght, let say 35. And for this wall disable visible to camera. Whole room is rendered ok, wall is in GI, reflection etc. but camera has good perspective. Sometimes with small rooms its much better this way then put camera inside the room and set focal lenght under 30 or move camera to the top right corner of the room No one really see camera doesnt fit in that room, still looks natural - camera position, angle and shot is much better. We are not photographers so we can use things we cant in real world.

Oh that is a good one! I never thought to try that, so thank you for the advice. BTW, the other tests look great, too, the lav ones just took my attention.
TY

Thank you. I used Siger Shader - Thin Film for Iridescence effect. Its free.

[voltron7]

I have that one, just never had a chance to use it, lol. Glad to see it works so nicely.

[Jiri.Matys]

Yeah, I know that. I tested it after several years I had it on my drive

SSS shader study with some dust on it.

[PIXELBOX_SRO]

looking really cool! maybe also add some dirt to it and glossiness variations.

How did you do the dust?

Thanks for the tip. Very nice method!

Yeah, but I wanted to see the dust and don't attract eyes to other things. Of course we can push it further, but I am happy with the result.

[Jiri.Matys]

Just new layer in VRayBlend. But set it up was a little bit tricky, very sensitive to all settings.

No problem, glad to help.

[Vizioen]

Nice looks like it has a volume to it, like a bump or small displacement.

[Jiri.Matys]

Updated wood.

[voltron7]

Damn that wood looks really good! Great fossil, and the background elements are nice fitting, too.
