Vray Interior wine glass problem

[claytonjamesblack]

A simple vray interior problem which someone can help me with. I'm trying to get the wine glasses to produce see thru shadows. I have read plenty of tutorials about how to produce the caustic shadows but I'm not getting anywhere. I'm using max 9 vray 1.5. There is something I'm missing!!

Can you render a blow up of the area, kind of hard to see;)

close up of glaees and shadows.

 

Shadows should not look like shadows made by a wall, ie have some light passing thru.

These are the settings I used for this scene...............

Cheers I will try it out and get back to you

The problem is solved. I turned off Vray : Caustics.

 

Still not happy with the results though. I just thought Vray caustics would give me the desired effects that the material with affect shadow has.

Hej! Clayton!

 

Its good that You are trying... ceep it so

 

that helps me a lot!!!- gret tutor for glass caustics:

see You later

I won't pretend to know anything about VRay b/c I haven't had the opportunity to work w/ it yet, but just a comment on your images. You got the shadows for the glass to work, but I personally like the shadows in your first image more. The second image is much brighter and I personally think that you burn out some of your detail w/ the lighting. I also liked the bowl where it was in the first image lol, but that has nothing to do w/ this. Otherwise, I envy you and all like you that can do this stuff, I'm still teaching myself 3ds and can only dream of when I can make stuff like this - its brilliant!

This may be one of the tutorials you already went through, but I find myself constantly going back to if for situations like this.

page 2 is really the page that helps address this caustics and vray issue.

 

here's a quick snipit I have almost come to memorize I use it so much.

 

" So to summarize:

1. If you use only object lights and Vraylights and you want caustics:

- enable GI caustics

- use good quality GI settings to make sure the caustics look sharp.

 

2. If you use max lights and you want the light to pass through refractive materials:

- use the affect shadow option for a fake caustic effect

- OR enable caustics in the caustics rollout and play with the settings for photon

mapped caustics.

 

3. If you use Vraylights and you want photon mapped caustics:

- Disable affect shadows

- Disable GI caustics

- Enable caustics in the caustics rollout and play with the settings."

Cheers that sums it up quite well.
