Do you have in your kernel "Alpha channel" checked and "Keep environment" unchecked ?

NO i didn´t


arrgh!

thank you atome... now it works fine!!!

I'm having trouble with this as well using 2.1 plugin and standalone. I followed the advice on this thread but I'm still having problems rendering the background in the cheetah hair sample scene. Please help.

what kind of help do you need?

well I can't render background objects in the cheetah scene? isn't that a supported feature?

you have to enable "ALPHA CHANNEL"

Yes, my settings are the same as yours in the screen shot, but no luck..

compare this scene with yours. I hope that you can find what's your mistake

Hi Aoktar,

Thanks your scene was helpful.

So basically in your test figurine scene the background is generated by sampling a material texture file which you have provided as well.

In the cheetah hair sample scene the background is generated by a background shader within Cinema 4d, and will render a blueish background as you can see for yourself if you download the sample scene and hit render with the standard renderer.

It appears Octane only supports background's that are provided via image files but not gradient shader backgrounds. Is this true? I'm just trying to understand what limitations are present so I can sucessfully avoid them. Thanks..
