Vertex Map - Mixed Material - long render times

[gizmoh]

Hey there,

attached you see a scene with a mixed material that´s based on a vertex map. Basically I tried to reproduce this tutorial with Octane

My question is, if my setup is correct because the render takes too long. The render itself is ok, but every frame needs around 60 seconds before updating.
I´m pretty new to octane and this board. I tried to find the answer in this forum before posted my topic!
