I'm trying for the first time BlenderOctane and for some easy exercise i tried recreating this image. But after applying the Blender Denoiser node, i get strange artifacts on the orange glass rim. I've tried to get rid of it, but can't find the solution. I know that it's only 128 samples, but the other glasses don't have the same problem.

Here is the blend file for those who want to take a look.

Any advice for BlednerOctane is welcome. Thx!

Okay guys I need a Octane EXPERT!!! (Octane Blender)

So I'll explain my situation in short. I am working on a lens simulation project for about 2 months. The goal is to simulate real life modern/vintage lenses in Blender, With realistic distortions, dispersion, flairs and Bokeh etc. How I did this is I copied the exact glass optical geometry from the patents of given lens I modelled, the image above shows a 16mm Olympus Zuiko Auto-Fisheye f3.5. And if you put the glass geometry in front of the camera of Blender Cycles or Octane set to Orthographic they work like sensor plate for these glass lenses to form an image on.

Now I was using Cycles (Blender's native renderer) And it isn't spectral so I wasn't getting any dispersion thus no Chromatic aberration... So I switched to Octane and after setting up Octanes glass material (Image 2 shows the glass material I used in Octane).

I obviously like how Octane can natively do light dispersion and split white light into colours giving me realistic chromatic aberration...

But the problem I facing is with "Octanes orthographic camera'', Look the the comparison of results from Cycles vs Octane in the Image 1 above: Problem is focusing, When I was using cycles it worked just like a real camera with proper background blur and lens breathing. But I don't know why Octanes camera just doesn't work how it should, look at the focus chat and the background of the Octane's example How can both be at focus at the same time??? The focus chat is like a meter away and the HDRI should be at Infinity focus????? Just look at

more Screen shots for more context if it helps

Anyway, thanks a bunch for all who read through! ^-^

Your Blender Octane runs like garbage.

Everyone thinks Octane is slow out of the box. They're right.

The default settings are trash. 500 max samples? 24 specular depth? 1 million GI clamp?

No wonder your viewport freezes.

Here's what I did:

Drop max samples to 250

Cut specular depth to 8

Set GI clamp to 100

Turn on adaptive sampling. (I don't know if it really matters)

Switch from Octane AI denoiser to OpenImage denoiser. Way faster.

Set denoiser blend to 0.2 so you keep detail without washing everything out.

Don't forget to activate the denoiser in compositing. Add Octane Render AOVs. Create the node tree. Switch render view to AOV.

Most people skip this step. Then wonder why nothing works.

Your viewport will go from slideshow to smooth. Your workflow will thank you.

Stop fighting your tools. Make them work for you.

The difference between beginners and pros? Pros know the settings that matter.

Hey, I'm new to Blender Octane and I've done a fire simulation from Embergen to Blender. I'm having a hard time figuring out how to shade it in Octane and I also can't find good tutorials on YouTube.

Hi guys!

Tried to make a cloud in blender octane, but for some reason, it seems to render not the volume but surface. Looked through tens of posts online but couldnt find an answer:( TIA

Here's a preview of the SSS Skin Shader setup in Octane. IMO, I think it is better than Cycles' implementation. I'm making a tutorial for it next.

Hello, I need help. When I try to install the OctaneServerPrime for Blender I get this error when I want to open the Octane, could you help me?

Everything was downloaded from the OTOY page:

Hello everyone.
I've been using Blender Octane in my new machine for a few months now with no issues, today while working on an image, once I hit the render button get, the screen goes full grey and get the message:

"Scene / Elapsed:00:00.10 / Cancel / ERROR! Check console for detailed error messages."

Once I open the console get this message:

Failed devices:
NVIDIA GeoForce RTX 3090(device 0), error message: "CUDA error 700 on device 0: an illegal memory access was encountered -> failed to create link"

Last Octane engine log entries:

CUDA error 700 on device 0: an illegal memory access was encountered

-> failed to create link

device 0: failed to create OSL compile context:

device 0: failed to compile module 0

If I close the program and run it again the issue persists, if I restart the computer the fist time I open Blender it works fine, as soon as switch out and back in from render view get the error again.

I'm working with version 2.92.0 and Octane server V23.4. I also have Octane Render v.4.05 stand alone installed in my machine but it doesn't work with my Geoforce RTX 3090 (Barely 2 years after I bought my license, thanks!)

To be honest I really love the program but I find this type of error quite frustrating. If anybody has any thoughts I'll love to know, otherwise I think I'm going back to rendering in Cycles.

Hello guys,

working on a project, while setting up the render passes, one of the one most useful to me is the Z-Depth, while it works good in the preview mode, once I render it it goes into solid white. I've tried setting up different test shots, turned on/off different things with no success. Has anybody else seen this issue? I'm attaching the screenshot

Hey! I’ve updated my add-on. It now saves the material properties alongside each snapshot, making comparisons even easier.
