Material converter

[J.C]

Hi, is is possible to improve Cycles material converter a bit?

It could:

• 1. Convert all image nodes to Octane nodes not only those connected to Cycles Principled node.
  2. Cycles Gradient could be converted to Octane Gradient map.
  3. Cycles Hue/Saturation/Value node could be converted to Octane Color Correction node.
  4. Cycles Mapping node to Octane 3d Transform node.
  5. Cycles Invert Color to Octane Invert Texture.
  6. Cycles Mix node to Octane Mix Texture.

We'll look into that, but it's not a trivial task for sure.

I've created a rudimentary addon that should be able to do the things you need. For now only a basic set of nodes is supported, but I might add more over time.

After installing, you will have a panel named "Octane Tools" in the Shader Editor. The first button converts the nodes. All the non-converted nodes are colored red. By clicking the second button, you can remove them.

You are the man! I guess it was not trivial

Not trivial, but not too hard either. My programming days are way in the past. So the code surely isn't as slick as it could be. But if it does the job, noboby will care, I guess.

Let me know if there are any issues. I will add more nodes little by little if I have some time.

Some ideas:
1. Is it possible to convert multiple materials with one click?
2. Is it possible to use simple Mix node instead of Grouped composite nodes.
3. Have you considered using Universal material instead of Standard one? Standard material does not have controls for BRDF model.

I've updated the addon. You can now choose if you want to convert to SSM or Universal Material. There's also a checkbox. When it's unchecked, the Mix/Add/Multiply nodes will be used instead of the node group. Still working on the conversion for all materials - it's a bit tricky for a non-pro.

Thank you for the quick update.

FYI ... you might have seen in the other thread, that SSM is energy conserving. In case it matters to you.
