Lasers bouncing in glass object

Hi!

I'm trying to achieve this look inside octane for C4D
[vimeo]https://vimeo.com/102437177[/vimeo]

This is real life footage from GMunk, but i'm wondering if I can achieve the same effects in Octane,

I've already tried multiple things but the lasers don't seem to bounce around in my object
If anyone has some tips or tutorials that would be great, thanks!

Hello,

The vimeo video is showing a real video footage but I suppose you are already aware of that.

This is a very difficult scenario for any uni-direction PT renderer, including Octane. As a pointer/starting point, there are a few elements required, such as (non exhaustive list):

• An appropriate mesh topology, thickness, etc. Modeling is key in such scenarios.
• Non-clamping/limiting render settings, exaggeratedly lowering "GI clamping" or the 2-3 depths parameters, for instance, would limit the renderer for properly tracing rays and letting them "bounce".
• Light "energy", since using strong enough light values make a difference in terms of "energy" and so, bounces, caustics, etc.
• PMC would likely be the appropriate kernel for complex light transportation scenarios, but does not support all features as the PT Kernel does.
