Volumetric/SSS rendering playground

[maru]

It won't work if you have your camera inside it. Use "global volume mtl" in "environment" section in Corona settings instead.

I still get something like fog, but no volume lights.

Volumetric scattering is available only in daily builds, not in A7.1 public release.

here's a new try at creating skin with the new sss , it's getting dark in the wrinkles..

[maru]

such renders always seemed scary to me :)

[Bigguns]

Updated the  sss volumetric shader with a blend with other mtl.

 I added the teeths, I will do a more proper shader for the eyebrows (and the eyes of courses...) and I will add the hairs tonight to see how it can look .

The subtle hair in the face is geometry?

Cheers.

[Bigguns]

yes all the fur are geometry.

Well that eye render is...frightening. Great texturing, but frightening.

I am hoping you will be able to finish this project soon... we would LOVE to use it as the promo image for the first Corona commercial release!

Great job Bigguns

[Bigguns]

Hey thank's guy's.

Keymaster : Sure you can use it once finished, but you know, if you do a skin shader ,I will be able to do much MUCH  better image then that , just to say :)  if it can  motivate you :)  ( I don't know how long it take to program the skin shader, if it take's 2 week's , I think it really worth it to make it now, but if it's taking more like 2 or 3 months I may understand you want to postpone it..)

I will work on it tomorrow and post some more images.

[Ondra]

I don't see how it could look any better ;) (well maybe ears...)

hello, how can i try volumetric render in corona?  i think great feature may be support openvdb in corona.

[Bigguns]

Keymaster :  Actually, it can look a  lot better with a true skin shader, believe me :) I'm the artist, you  the programmor haha :)
There is also some bugs, like everywhere there is wrinkles, it's getting dark in those wrinkles... look odd. ( it seems to be the bump the problems, I'm doing test on it now..i'm not 100 % sure it's that but look like it is)
second thing, the front scattering  would be much better with a true skin shader, we will feel more the deepness of the skin instead of more plastic like now.
Third: there is no prepass ID like in vray skin shader so I cannot make things blend perfectly togheter.
fourth: it's really slow to render compared to a skin shader since it's volumetric thing.
fifth: It's hard to set up to mimic skin since it's not done for that purpose.
six: Backscattering ( in fact all scattering ) would be a lot better with a true skin shader .
seventh: the light do not affect the object like it should be(because it's volumetric thing and not solid I guess..), I had to play with the values to get something closer to normal.

EDIT : also it lack a scatter radius fonction, etc.

I'm doing these tests mostly for you, trying to show you something else then arch and to motivate you to do the skin shader ( even if it don't have a hair shader for the first release , just saying to peoples it will come soon so peoples know it :) ) and do the skin shader, but as  I said, I have no idea the time it take's to implement it.

Edit *  :  delete my quote please lol

I will post some new images tonight :)
