pre-23: reflections from emitters

[rman1974]

Thanks for replies, guys. Now I understand - in current octane version impossible to get emitter reflection in low roughness materials like lacquered wood or carpaint. That's sad.

Here my quick test, I had to inport it in Rhino and check the normals in order to have proper reflections

where are these sample scenes located for download?

Normals is OK - they don't need any correction. Problem (or feature?) is in materials. Just try to set roughness of table material to zero (0.0000001 actually) and show me reflections from emitter. I want to see clear, non-glossy reflections.

Here you go mate, I did not say that Normals were wrong but just checked, anyway here is your file 'as is' but with table material roughness set to the lowest value 0.0000001

and still no joy

and then the re-imported from Rhino (in my case, I use Rhino) and I say just re-imported, no normal set of any objects, only need to re-apply materials but you can see the difference, actually if you try to re-apply the material to the table you should be able to get it right, maybe some bug in your modelling software exporter or else, I can't say.

Interesting test though..

WOW! What a BUG! Procedure of getting non-glossy reflections looks like voodoo ritual. I'm going to try it. Still not a word from octane team - seems it isn't much interesting.
BTW thanks for testing.

I dont think it's a bug in octane, but moreso a bug in your exporter, obviously it works, as was shown after being exported from a separate program. No voodoo needed at all.

cheers

I'll try like this again tomorrow. Hope this solution works.

Why we not see a word from developing team about this? That's strange

If this is a exporter issue, the Octane developer team has nothing to do with that.
The plugin developers and the Octane developer are two different groups.

On the other side, if one exporter has an issue, we should know which one he use.
