Title: Strawberry
Post by: marioteodoru on 2014-11-24, 02:07:49

Hello,

I am trying to achieve organic SSS, but i really don't understand the relationships between all the parameter. Can anyone help me out with some advises to obtain  a realistic look ?

Thank you!

To be honest, I would wait 1 week for corona 1.0 to be released, then you will have proper SSS and can take a correct approach rather than faking it.

Hello,

i'm interested more in understanding how each parameter affects sss. there is a relationship between translucency and absorption distance which i'm not able to see how it works exactly.

how do u know it's gonna be released in a week ?!

:D

Read the Blog,

Prices & Release Date of Corona Renderer 1.0 for 3dsmax
"Sales will start in November. We do not want to give you exact date yet – we still want to cram in some new features. Let’s leave it as surprise. We will try to deliver Corona Renderer for 3ds max as soon as possible."

What makes you think SSS in 1.0 will be any different than current one?

Hello,

i'v read the blog, and we're still past past half november. So....

Anyhow, keymaster, maybe you can help me a little bit. Looking at the material printscreen, do you think i can do anything to improve the material now?

Thank you!

Hello,

I'm coming back with a request from help, maybe from keymaster if it's possible.

I can not make it work, after 4 days now, of trying to find a working displacement.I tried a lot of variations from zbrush multimap exporter. I will make another test with a different render, but basically, this should work.
Did anybody meet with this issue? Does anyone here has a advice for me?

Thank you

My guess would be - too low resolution and too low bith depth image is used for displacement. Because displacement maps aren't filtered in Corona, you get those perfectly square artifacts.

I would blame displacement as well.

Is this grid still visible when you:
-disable bump map and enable displacement
-disable displacement and enable bump map
?

Hello,
thank you all for your input.
I just gave up on the AUVTiles zbrush uv map, and made a regular uv map. It seems to be ok now.

So i'll get back trying to nail down the SSS
