- roughness and reflection intensity should are working
- IOR 0 means no reflection and not metal reflection

I'm sorry, but it's not clear what you are asking for here. If you provide specific rules for material conversion, I can take a look. However the existing material rules were established by users early in the plugin development process, and no one has since indicated any issue with them. If you think you have a better set of conversion rules, I can put out a test release with these rules for people to comment on. However the conversion rules would need to be detailed, clear and unambiguous.

You could use change type(copy similar settings) but it must be done one by one material.

Is there any batch material conversion process besides the rhino->octane conversion?

Or can the conversion formula be xml'd?

Is there any batch material conversion process besides the rhino->octane conversion?

You can rightclick the settings tree and "Convert All Materials to Octane Materials". It is not possible to write a command to convert a Rhino material, because there is no way for a command to know which material is currently selected in the Material panel.

Or can the conversion formula be xml'd?

I don't think this would be viable. For example, the material conversion rules for Modo Materials to Octane Materials is very accurate - but is also quite complex - not something you could define in XML. It is easiest to code the rule directly into the plugin.

So are you inferring that the material conversion formulas for mood plugin are superior?

Is there a cost to the complexity?

No cost - just took someone with a deep knowledge of Modo (ie. Funk) to work out the conversion rules.

We could also use rhinoscritp - don't know how it handles materials (I bet it does), but usually gives far more options than rhino commands

I doubt this will work, because I don't think it's possible for a script to know which Material you have selected in the Material panel (ie. it won't know which Rhino material to convert).

Hi Paul,

I understand if you don't understand my words, but my screenshot shows that something is wrong. OK, here a new example. I tried to setup the same material - green one is Octane material and blue one is Rhino material. Good to see, at the Rhino material is missing the fresnel effect and the roughness. If I play with the Rhino material than I get the impression that reflecetivity is connected to the Octane IOR slot, gloss finish is connected to specular and the IOR slot is not connected. Specific rules for connection: please connect the Rhino IOR with Octane IOR, the Rhino gloss finish with the Octane roughness (rule: roughness=1-100/gloss finish) and the reflectivity with specular. Also a Rhino IOR=0 means no reflection, please don't use it for metal.

Here some more examples of the current wrong connection

plastic material with full clear reflection plastic material with specular/reflectivity = 0 Rhino file is attached. Good luck.

Micha - how did converting a blue Rhino material result in a green Octane material?
