Hi aoaktar,

I found a problem or maybe a bug with Mix Materials inside C4D, but i think it is a normal behavior with Materials from C4D.

When creating a mix material and filling it with a for example an Octane Diffuse and an Octane Glossy Material, everything is fine and works so far.
But when I use the function "delete unused materials" in the Material Manager, it deletes the Glossy and and the Diffuse Material, because only the Octane Mix Material is used with an object. Sometimes the Mix Material stays the same after that, but cannot be edited anymore, sometimes it is completely reseted.

Is there a way you can implement the Mix Material Function avoiding this issue?

Thanks so far,

hi, it's a known issue, as a workaround, you can assign the two materials used by the mixer just before the mixer tag to the specific object.
in this way octane will read only the last one material tag and c4d will not delete the two materials becouse they are assigned
