Hello,

it seems like the Octane volumetric spotlights does not really behave as expected, to my knowlegde, see attached video.

System infos :

OS : Windows 10.0.21292 Build 21292
DCC : Cinema 4D R23
Octane version : 2020.2 R3
GPU Driver : 461.40 Studio Driver
GPU : RTX 3090

Hi,
everything seems to work as expected here with Volume SpotLight in 2020.2-R3: It seems that you have high Density and Scattering values, at the moment.

Everything is at default value is the thing.

Broken and unusable for me too.

try and say what you get with this scene? And @Dazhai, send your scene which is not usable

Yup, just tried it after some time again. Overlapping causes problem, it renders incredible slow and the biggest problem: the light source completely blows out AND doesn't resolve even with 16k samples.

@Ahmet, your example shows the exact same behaviour.

Are there any good resources on how to use volumetric lighting in octane? I always struggle to get a decent results with relativley good render times.

It is expected without a proper digital-imaging pipeline.
There is this page and this one that will help.

A call for my shameless-plug.
