OTOY Forums

Hi, I've been contacting Otoy support for the last two or so months in emails about this issue but nobody really knows why its happening, My last resort is to ask here to see if anyone has any issues, Using the most recent or any very new version of octane for cinema 4d results in the denoiser performing very poorly, especially on the edges of subjects or objects, appearing noisy and weird, The main parts are far too blotchy & uneaven too. Here is an example I made: https://i.imgur.com/gJUS0qn.png its very clear on the lanterns especially, Please help! thanks.

Yes, your lantern objects are pretty noisy in the new renders, but that could be caused by a lot of different things in such a complex scene. As usual, if you can provide a stripped down example file that demonstrates the problem, you'll probably get a better response.

How about sharing just one of those lanterns in an otherwise empty project file? In your example the problem seems to only be in whatever kind of volumetric/subsurface scattering material you are using. Is that the only place you are seeing the problem? There are far too many questions to go over them here.

What kind of troubleshooting have you done already? Check this post out:

I've already done this with the guy named 'Beppe' It is not a scene specific thing, this is an entire program issue, doesn't matter what is in my scene it will appear bad like this, especially with the edges, always noisy & weird. Heres the lantern anyway; https://uploadir.com/u/q6e0g782 But I doubt it'll help due to it being an entirely program specific issue, I've tried uninstalling all drivers (DDU) then re-installing only studio drivers, I've tried turning debug mode on in nvidia control panel and a few more. I have more than enough ram (64GB) and I recently upgraded my GPUS (from 1080 to 2080ti) and still have the same issues, Its only with the new versions, My older version works perfectly. I'll look at the post now tho!

Hi,
as I told you on Support, the single lantern works perfectly, so we need an entire example scene that clearly shows the issue, otherwise it is impossible to investigate.

You're right, Beppe, the lantern seems fine to me, too. It must be a more complex issue, but it's always worth trying to simplify, first.

Tektah, you specifically came here asking for technical help from the community in general, so in order to give any reasonable feedback, we need more information. Honestly, though, if Beppe can't figure it out, it's probably a particularly odd problem.

The screen shots you shared are from a complex scene, with a lot going on, while the single lantern scene file you shared seems to behave as expected, without any extraneous noise. If I were in your shoes, I would build the simplest scene I can that still clearly demonstrates the unusual noise problem (and I mean really simple, like one cube and one light, if possible), and share that with Beppe, and/or the forum. As described in that trouble-shooting post, I'd also share the various things I'd tried to isolate the problem along the way, and the results of those tests.

Absolutely, here is a extremely basic scene with a random hair model of a game, Extremely basic. Just to show you that this happens on *every* thing I do. Here is a comparrison picture: https://uploadir.com/u/4sbmlln1 Look at the top left, the ugly noise on the edges and such. Here is the scene file: https://uploadir.com/u/0uvrvzen Same render settings etc.. 100 samples for both, everything is the same aside from the octane version.

I don't have a good answer for you, but I played around with your sample a bit and have learned a little. From what I could see, the problem is specifically with the Universal Material in conjunction with Transmission when applied to concave, reverse normal polygons. At least that's the only way I could reproduce the effect.

Here's a simple demo scene, and render. Something funny is definitely going on, as you can see in the funky two-tone results. The odd noise is happening at the boundary of the tonal change.

Maybe this will be useful to Beppe & Co.

thank you for doing some testing, Really it means a lot. I hope this can help the developers help me, I will defo keep your info in mind though!

Hi Frank,
big thanks for isolating the issue, the Universal material is not correctly setup in this case, you need to change the Transmission type from Specular to Diffuse in this case: ciao Beppe
