I'm still playing with density but it has allmost no effects.
From 1 to 150 I barely see no changes...
The light should be massively changing to the corner because of the thickness varying...

PS : And another topic, how to make slight reflection on that ?

Thanks Paride!
It's much simpler with a diffuse mat than with a spec mat

Hi,
I'm trying now how to make a foam material (as in the references uploaded).
But I still cant figure out how to set up sss.
The color is dull and too dark, the light is weird...and render is awfull.
It look like bad wax or soap but absolutly not foam.
(I started from a sss specular material ...

Ok Paride thanks for the help.
I'll have a look at the free version of Forest pack.

Ok.
Thanks Paride, I will try.

But I'm affraid it wont be enough as I would need 10x more particles do make the vegetation in my scene...

Yes 1 of the 2 monitors is connected to the 980ti, you think that's what take 1.206 Go away?
I run Win7pro

When redering with 3000 particle, the task manager indicates that Ram stays under 20 Go usage over 24 Go total.
So it's not a Ram limit problem I guess.

Also what is strange is that the octane viewport indicates 4.794 Go available VRam.
Shouldn't it be 6 Go available as only the GTX980ti is active?

Can you tell me what you mean by "depends on memory"?

Bad memory on PC? on GPU ?
Insufficient amount of GPU memory?

Sorry for posting so late, I was off for a few days.
Here's a scene.
A simple Pflow scattering teapot on a plane.
It renders with Birth set to 2000.
If I raise the birth to 3000 it crashes.

Seems to be a memory issue...

Particle crash.jpg Hi,
I have a simple plane on wish I scatter a meshes (7000 faces) using particle flow.
Each time I set particle birth to more than 1500 instances Max crashes when opening OctaneRender viewport (or launching a render).

I think 1500 instance is not a big deal for particle...I ...
