Beckmann GGX BRDF

I read a little bit about the new BRDF models on Aoktars Help manual, all that interesting stuff about conservation of energy, and so on.
Which brings me to my question: when creating new materials, why is Beckmann (for example) not selected by default? Why is it still "Octane", when it is not fully functioning?

Agree, there could be an option to set user defined model when creating a new material.

You can write a short python script to use for creating any octane material or others.

me neither
@aoktar: this was just a suggestion for a future release maybe. I mean, since you mentioned it by yourself on your own site... I think, that you're doing a great job, btw

It's not requiring to be a programmer i think
Here's sample scripts. I hope you understand that I cannot do every request. You can ask to someone for helping you who knows the python in c4d.

You can set your own defaults in C4D.
Once you have it set up the way you like it (BRDF model, etc.), go to Edit>Set As Default. It will save it in your presets folder in the content browser. To reset just delete the default from there.
This doesn't work if you create new materials from the live viewer though. You have to go to Create>Shader...
