Hello all, thanks for peeking in. There is a new lighting challenge at CGTalk that is an underwater scene. There is some interesting discussion going on in the thread currently. http://forums.cgsociety.org/showthread.php?f=185&t=1061572 One of the poster’s mentioned Snells Window ( http://en.wi…

When in doubt, ask Vlad! That’s awesome thanks for your help on that, and the scene file Just out of curiosity, could you explain the logic behind placing the camera inside a bubble/sphere? It works perfectly but I probably wouldn’t have ever considered this approach Thanks Again

Because of the fog color that I used in the VRayMtl material, which is the same material on both the bubble and the water surface; otherwise V-Ray won’t know when to start and stop the fog. It also helps V-Ray to compute the correct IORs. Think of it like a real-world underwater camera case …

Perfectly understandable logic, remembering that underwater camera’s are indeed wrapped in a bubble (it’s always the little things that count) Thanks again, I’m sure many people will find this really helpful :wink: Ant

Thanks for the sample scene Vlado, so simple… -Michael

Wow step away for a weekend and there is 2 pages of posts! (My face is red.) Thank you all for posting, I’ll have some time here Wed to play with this a bit and learn more about things in this regard. Thank you all again for posting. EDIT: To make sure I understand how Vlado got what he did, it…

[image] Anyone willing to share some settings for realistic looking fireplace fire? anchovy: That’s pretty amazing, this might seem like a lame question but how did you know to do that? I did a number of underwater shots when I was a TD at the Orphanage. We used Brazil there but the premise i…

It works as well as Vlado’s image suggests, little bit of noise or displacement on the water and some objects above it (and HDR environment of course) and it really comes to life. Just adding a seabed to my scene which should reflect beautifully in the area outside of snell’s window, with some caust…

The orphanage huh? Very cool! Thanks everyone who posted here, it’s a great lot of information. I started setting up the scene last night for a bit after work (late), got the water volume in, a sun/sky and a vray cam. I tried to get some fog color for the water material into my volume but it was…

Hi Deflaminis, try the water as a surface rather than a volume. When the camera is within a bubble, the void between the water and the bubble will become your volume (hope that makes sense) This will ensure that your fog and ior work correctly, this is what I gathered from Vlado’s sample scene (def…

Hi Richb, thanks for the post. I downloaded the checked out that scene file you mentioned, it’s amazing in its simplicity, yet I find I don’t fully understand why it works. It’s pretty amazing if the distance between the bubble and the plane for the surface of the water can be viewed by vray as if…

I did a number of underwater shots when I was a TD at the Orphanage. We used Brazil there but the premise is the same. I admit I like Vlados suggestion and I want to try it here in a bit.
