Hello

I did import model from XSI and like to render now, but what I like to do is render only the model, not background color, so I can composite background image in composite software.
I've been looking for the option in Octane, but can't really find it : /

Can anyone tell me how to make alpha transparent render image?

Thanks
Daniel

in the render kernel seetings (where you switch between direct lightinh, pathtracing and pmc) just tick the "alphachannel" checkbox ;)
