Hello,

I'm using Octane 4 and I'm experiencing a problem with the walls. Please refer to the following image;



1. It's a normal, flat wall yet there's strange light circles on it, including various other artefacts.
2. The beams on the right are going through the wall and where it happens there's a mad amount of light bleeding through it.
3. The ceiling is touching the vertical walls and the scene should be properly closed yet, as you can see, there's light emanating from almost all of the seems.

This is the second scene that has had this issue in a row and it's always just walls. everything else is fine and I am unable to recreate the problem on anything but the walls.

Any help would be appreciated, thank you.

Try moving the wall 1mm so it is not that the center of the scene.

Tried moving it, tried changing textures, tried many a thing. It still looks like something is applying some kind of odd smoothing on the flat surface. Here's an image with the walls in darker diffuse texture. The one on the left is still in light blue.

Hey Paul, I went through all the settings again and it turns out it's Ray epsilon that was the problem. I had it set to zero. Setting it to "1e-05" fixes the problem. Not the first time that setting has caused me trouble either.

Sorry for the bother but I do hope this'll help someone in the future. Cheers.

I had some strange occurrences with flat surfaces, where the mash density was quite low, quite often, too.
Beside the ray epsilon setting, I most of the time forgot to uncheck "Smoothing" in the material tree.
You can get some quite funny and unexpected results with this setting either

That was my first thought too. Because the effect really does look like smoothing gone wild. Although, I did forget that both Poser and Octane have smoothing settings so I'm quite certain one of them was on at all times.
I set Ray to zero because there was a point I couldn't find 1e-05, which is the only setting that doesn't cause adverse effects. Setting it above zero causes all the figures with displacement maps to show black rings at each point they interact with another object, while setting it to zero causes...well, this apparently.

But I'll keep this in mind in the future as well. Thank you, Erick.
