- why not to do the same for Image node ?

Because it is not available in core side

But you added great "switch texture" node that not only resolve problem but it even give more functionalities. Thank you very much for that ! It doesn't work with procedurals.

Hello,

If I change the value of the 'Cone angle' in the 'Spotlight distribution' node of an area light, the instances of this light are not updated in the LV. I need to active/deactivate each instances. ('Resend the scene' doesn't work). Is this normal? Thank you.
EDIT: Tested with the R6 version (see now there is a R7...)

There is issue while loading PBR textures with auto-connect feature. It set their legacy gamma to value 1 instead of 2.2 so they all are too bright. Only Diffuse texture is load correctly with gamma 2.2

There are not any detectable update messages in instanced node. So it's not updating, activate/deactive method looks like a work-around.

Hi, PBR textures are usually saved in linear gamma for all maps, except the Diffuse/Albedo map.
That's why we've chosen to do the same for the auto-connect feature.

If one of your materials needs Roughness/bump/spec/metallic/ etc maps to be set to 2.2 gamma, then those materials are outside of the usual behaviour.

Can you upload one of such materials so we can take a look?

You can test some free asset from store.graswald3d.com. The problem is with translucency images - they are the same as albedo - they need 2.2 gamma.

It's better to set the rest of them as non color data but leave default gamma value as it for compatibility.

Sorry I dont have an account at Graswald but I tested it with Quixel Megascans assets and there the translucency map also has to be interpreted lineary (1.0 Gamma) to look correct.

We could perhaps set all except the albedo pass to non-color data + 2.2 Gamma, which would technically do the same but I'll need to check first, if thats actually true.

Absolutely no - it will look way to bright ! Translucency is an albedo, color data but brighter because it simulate light scattering inside thin leaf.

If you will use C4D Quixel Bridge plugin to load Quixel asset to C4D you will have proper Translucency 2.2 gamma.

For linearizing gray scale images we have non color data type as manual says.

Also gray scale inputs should have type set to float

After installing Octane 2023.1-R7, I am unable to launch C4D. The C4D version is 2023.2.1.It consistently gets stuck at 'Initializing plugins 100%.
Everything was functioning normally with Octane 2023.1-R6.

You might double check the Octane plugin folder to make sure all non-C4D 2023 components have been deleted.
