A bit late with this answer, but octanerender mainly uses wavefront .obj files as input, and their materials is incompatible with anything at all(that's expected tbh), so basically all you need is to export .obj and tweak materials inside of octane.

They have free demo on their site, so anyone can test it

Aha, i wasn't sure if houdini embeds OTLs into hip files or not. Here's hda.

Basically it's a very simple procedural lightning with randomized seed based on destination point coord, so every lightning in a pack differs from others.
Probably nothing new for you guys, it was made to refresh my houdini knowledge. Probably i will make more advanced version with forking as a python sop soon, seems it's easier for to just write little lightning(src, dst) function than make all these node trees.

Here's the results, i was doing that just for training purposes, think the next one is gonna be easier to implement as a python sop.
