does someone has a trick to remove all Octane materials in
a scene?
One of my clients who does'nt use Octane wants to open a scene i've made and tells me he can't
open it because of Octane plugin missing, he's on Mac Os and this makes its LW crashes.
The big point is that there's a bunch of objects and surfaces in this scene, if anyone had an idea
to avoid me spending two hours deleting these materials

(the surfaces has also LW classic materials attached to them so i can't just copy/paste a basic
surface on them)
Big thanks to all
Olivier
