Custom Material Previews for Node Materials not working...

[ulrichGTAV3]

Hey, some time ago I created some custom Material Preview Scenes based on the standard "Arnold Sphere.c4d" file. Had to update them a couple of Arnold versions ago, but overall they worked fine and helped me to distinguish all my fabric, leather, metal and rubber materials at one glance. 

Now I switched to node materials and now my custom material previews are not working anymore. I can still use all the different previews that come with arnold, but my "cloth", "candle", "gem" etc are defaulting back to a sphere.

Is there anything I could do to make them work for node based arnold materials? Maybe even batch apply them to multiple materials at once?

Thank you very much!!

Node Materials do not support custom preview scenes natively, I expect this to be implemented by Maxon at some point. The ones shipped with the plugin are currently hard-coded. You can set the default scene in the Arnold Preferences, but that will change it for all materials.

Thanks for the info... Unfortunate, but I will be able to live with it 😉

If I'm not mistaken, you added more material preview models. Very awesome!!

Yes, the preview scenes were updated in C4DtoA 4.2.2. Added a new cloth and volume preview.
