Open the attached scene and render to live view. It gives me a crash here 100% of the time.

Weird, if you merge the scene into a new empty scene, it doesn't crash: ciao,

Im 99% certain this crash is due to the use of analytic lights creating post volume effects. I suspect your fresh c4d file has reset the Post tab in the octane render settings.

If I copy paste this scene to a new c4d file it works, but once I enable the post glows and specifically 'Light Beams' in the Volume effects tab, it crashes again.

Weird, I have no issues with Post Effect/Volume, even if I enable the PostFX AOV in Render Settings: ciao,
Beppe

I have forwarded this scene to the octane team as it seems to be an issue in Octane itself
