Grant Warwick- Mastering Vray: Material Ideas Needed.

[grantwarwick]

Trying to achieve a volumetric Jade material using vray blend and SSS2-

I've mapped the Fog color attribute with a tone mapped marble texture and even though the material doesn't look realistic, I think I can get some really nice looking effects with this approach.

Gorgeous. Really nice work grant.

I admire ur patience with those render times :O

Ohh some lovely materials!

+1 for white translucent medical type plastic like the tupperware posted earlier.
Also it'd be great if you could bear us Maya users in mind too when you explain things too...

I know Maya but haven't experimented with the Vray Render. Probably safe to say I won't be covering it until I knew 100% what I was talking about.

Working on this tupperware shader now!

WIP Of that bastard semi translucent plastic.
This isn't physically based and I've had to hack the look but it's the closest I've gotten so far.

Glad it's not just me. I always struggle with white translucents. Looks good though!
I guess us maya users will have to make our way though with a bit of detective work.

Yep the polyethylene is a bitch! But that's looking pretty good. Not sure what all you have going on but im sure it takes a bit to render. The real trick is its not generally glossy in the reflective component but it is in the refractive and it also certainly accrues opacity based on volume. Yep its a challenge, and The best results ive gotten so far are based on vray fog. I really want a volume shader vs the only way of getting the effect is through an atmospheric. And by the very nature of it its slow.

Volume shader or texture would be amazing.
Using the negative fog attribute by itself would be so useful.

[jacksc02]

Grant, could you not use the environment fog?

Chris-

Funny you should mention that. I was just running a test last night. Ive used it before encapsulated in a glass material but besides the expense there are other downsides. Its not portable like a shader is and Im not certain that the interaction of the glass and the fog is as you would expect. i too really want a true volume shader with reflective/refractive controls as well as scattering.

Here is a simple example using brute force. I know you can get better results but its not fun.



FR has a volume shader, but I haven't used it so I cant speak about how well it works.



Brazil had a great volume shader back in the day.

The brazil volume looks quite interesting, was it fast to render?

[Mokiki]

The last time I played around with environment fog inside glass it was just too expensive to render. Only came around to do a couple of tests before I lost patience :P.

It wasn't fast, but it was fast enough to be an option, and I loved the results. So far I haven't found that encapsulating a Vray volume fog inside glass to be doable in a production sense. I wounder if it was a dedicated shader if there wouldn't be significantly less ray calls and thus a lot less expensive?
