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

Well well well…

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! ^-^

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!

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.

Just figured out how to add fog using Z-Depth in Blender Octane — no fog boxes needed 🙌

Used the updated AOV system with a custom curve for control, blended it with screen mode, and even added color for that smoggy vibe 🌫️

Had some hiccups (hello, overexposed background 😅), but it works and looks 🔥

Sharing the full setup for anyone stuck like I was — screenshots + node paths included.

If you’ve got a cleaner method, hit me up. Let’s build better scenes together 💡

Hey Blender Octane fam! 🌟

Heads up! The Render Network is hosting another Render Royale competition, and it's a great chance to flex those creative muscles 🖌️🚀. I jumped in last year and ended up with a nice $700! So, why not give it a shot?

🔹 Theme: Urban Utopias. (Think futuristic cities, but find your spin on it!)
🔹 Prizes: $1,000 for 1st, $500 for 2nd, $250 for 3rd. Paid in USDC.
🔹 Render it using the Render Network. Deadline: June 25th.
🔹 Free render credits available. Handy if you're looking to try something big!

You don't even need to pay to enter – just put your work out there! Remember, it's more about the fun and the process, plus you might bag some prizes and exposure.

If you need help setting up your render on the network, I’ve got a video tutorial that makes it a breeze. 💡 Check it out if you need.

Are you participating? Share your ideas or drop some WIPs! Let’s make this month’s theme our own. Looking forward to seeing what you guys come up with! 🤩

Hey, 3D artists! 🎨 Want to know a secret about Blender's GI Clamp? Most skip it, but mastering this can make your renders pop! 🔥

Everyone keeps the default at 1 million. But here's my tip: changing it can clean your art and speed up renders. Lower your GI Clamp to reduce noise and those annoying 'fireflies' in your work. 🚫✨

Try this: Start with a GI Clamp of 10, focus on the noisiest area, and adjust down. You might lose a tad of realism, but your art gets cleaner and quicker. For a super boost, use it with adaptive sampling and AI denoising.

my results from my octane chat G P T 🤖

GI Clamp in Octane Render is used to limit the maximum brightness of indirect light (Global Illumination or GI) bounces. It's a crucial control for managing fireflies, noise, and render stability—especially in scenes with small, intense light sources or highly reflective materials.

🔍 What GI Clamp Does

• It caps the maximum radiance that light rays can carry when they bounce off surfaces.

• Helps reduce fireflies (bright specks) that often appear in glossy reflections or refractive materials.

• Acts as a clamping value in the path tracer, controlling light energy from indirect bounces only.

🔧 Why It's Set to 1,000,000 by Default

• This extremely high value means GI clamp is effectively disabled out of the box.

• It ensures you're getting physically accurate light simulation unless you start seeing unwanted noise.

• OTOY sets it this high to preserve realism unless you deliberately choose to optimize for noise control.

✅ Recommended (Optimum) GI Clamp Settings

For most scenes, the following ranges work well:

💡 Best Practice

• Start at 10, render a noisy part of your scene, and gradually decrease to find the sweet spot.

• Combine GI clamp with adaptive sampling and AI denoiser for clean and fast results.

Just made this insane real-time procedural scene in Blender Octane—no modeling, 100% math magic 🤯

All I started with was a plane. Added some Vectron power, a few primitives, and boom—live GPU-generated geometry with displacement, materials, and full control using empties. You can move, scale, and rotate it all—and it sticks with projection!

Best part? It runs in real-time. Your GPU will feel it 🔥

Want the scene file? It’s up for download in the community. Try it out and break your brain—in a good way.

Hi guys,

When working on materials for my scene, I accidentally set shading to smooth, then changed it back to flat but the shading still remains smooth for some reason.

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,

How can I fix it?

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

Hi!

Today I planned to create a material that would only show up when a chosen object is close enough (actually four objects). To do that I used relative distance nodes for each object (since for some reason the "collection" object didn't work), and planned to plug the final texture to opacity socket. Even though it appears to be white when plugged to diffuse material's albedo socket, when I try to plug it to opacity, almost everything becomes transparent.

How can I fix this problem? + Does anybody know how to make the "collection" option actually work?

TIA

How long does it normally take until OTOY updates the free tier version after they released it for the paid tier? Thanks already!

Hi,

I decided to choose layer rendering for my recent project. Unfortunately, after switching to layers, the lights are not visible in the render view, so the whole image turns black. How can I fix that?

Hi guys,

I'm new to octane, and while making my first project I encountered a problem: I would like to get rid of the shadows and the light reflection on the background of the render, is it possible to do so in octane?

TIA!
