I usually keep quiet on forums. Usualy i just roam around, but this question is really interesting, as i would be delighted to see Octane integrated into SU.
And i really would like to ask Otoy team when it will be released, but instead i will rather ask if it will ever happen?
Is it planned at all ...

Yes, you are correct. They should not give caustics like a solid body and it does not (there are differences in KT between hollow and full cylinders)

Good point.

If it'll work nice with Octane, then i will buy myself a licence and conquer the world with it.

And ...

Ok, thank you.
It really starts to make sense.
Yet this creates one more question.
How could one possibly check on the scale of the model within Octane?
Honestly, i just followed info seen somewhere, that while exporting from SU i should set units to meters, and so i did.
If this is wrong i'll have ...

Hello.
I am kinda fresh in here, as i have found Octane just about week ago.
I have rendered few scenes and results are good, but then i wanted to make a test on caustics... and then problems started.
