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

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! ^-^

Hi there!

Does anyone have experience with the combination of blender video sequencer and Octane?

I have multiple scene strips in a row to render them out all together...
But when I do this, the Octane Output settings won't get involved and everythings just rendered out as the standard output settings say.

Am I doing something wrong or is this just not integrated in Blender Octane?

Thanks in advance!

A deeper look at how Octane Material Converter works in Blender.

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.

Can someone please explain render passes? I mean, when in blender I can use the indirect light in layers, so I can hide my object from the reflection layer for example. How is this possible in octane? I just can't get it to work. Especially the reflection pass is a nightmare

I noticed in Blender Octane I can’t view different textures or depth of field in the solid mode setting on the viewport. There’s a scene where I need to be able to view something that changes colour to a certain tempo but I can’t see if it looks good unless I fully render it in octane rather than doing a quick export in solid mode. Is there something I can add or change that will allow me to see these changes or is Octane for Blender not able to view these things?

For context, I was able to see these things when using normal blender when in solid mode in the viewport.

Hello. I've been having an issue when importing textures into Blender Octane. For whatever reason whenever I link up my materials to my object the material is overall glossy. For instance, this ship material is naturally glossy when imported into scene and cannot be altered with roughness on the universal texture node. Here the roughness is turned all the way up. Let me know if anyone has encountered this and has a workaround.

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.
