You have threshold/cut off set for the glare/bloom.

No. It's all set to 0.0.THats why I'm a bit confused.

Colour Picker is also broken in this version. It doesn't see to do anything.

Hi mbetke,
it seems to works fine.
Color picker? Balance picker?

Ahh sorry. I mean the white balance picker.

I can pick the white balance once in the viewport. But nothing happens when I try to adjust the "White balance" in the Imager settings (F10) afterwards.

Hi mbetke,
ok, then not using Octane camera, thanks.

It seems that atmospheric volume doesn't work (to have fog effect in the scene) 2019 version works fine. This version it's either black screen or no volume Something changed?

Medium radius has to be very low and absorption cannot be used anymore. And having low med radius makes fog look flat and same

and look at the spot light in fog. It doesn't even act like one. (because octane volume light is a strange mesh unlike other vray's etc )

Second problem TYFLOW cannot be rendered in 2020.2 octane. 2019 works fine
the scene is attached

Hi coilbook,
SDK developers have made changes on the step length of the medium node; using PT, "emulate old volume behavior" usually solve the issue.
In DL AO, a workaround I think is to have the Step length value higher as you did.

Thanks What about tyflow?

@coilbook :
If you want to see something in octane you need to add a "Mesh" operator in your event. With "Triangle Mesh" and uncheck Render only.
If you want to render a lot of instanced objects you must : (see pict)
- add "Mesh" operator and check "render only" if there is really lot of object and it slow down max viewport.
- check "enable Particle interface" in tyflow settings.
Works very well.

Question to Paride :
When we need to use a gradient to color tyflow particle depending to its age, octane render gradient don't work, but max's plugged in a rgbImage node is working ?
