Does dispersion not work in the Octane Layered Material?

I'm trying to recreate the Diffraction Grating in Octane from https://everdrone.pages.dev/blog/diffraction-grating-octane#silicon-material
They use two objects there: one with a Metallic material and another with a Specular material. It works that way.
But shouldn’t the Octane Layered Material be ...

Is there a way to increase the gradient scale? For example, like in After Effects (when you stretch the gradient, it expands). Or maybe a separate pop-up where you can zoom in on the gradient?

Unfortunately Woodgrain is not even close to as good as Advanced Wood. Advanced Wood is made with OSL (AdvancedWood.osl attached). It would be great if Otoy could tweak OSL to make it work as well in Octane as it does in other renderers.

How do I get Advanced Wood map to work in Octane? Which projection to use to get this result?

That's right, the current implementation of the FP color ...

Unfortunately unfreeze doesn't work. 3d max constantly freezes or crashes.

Hi neonZorglub
'Enable Extra Log' checkbox and 'Reset default settings' unfortunately doesn't solve the problem.
This appears to be a problem with 3ds max 2025.2. There is no such problem in version 2024.2

Win11, 3dsMax 2025.2
I have a strange bug, if I use Octane Render, and click on the 3dsmax ...
