material on singles surfaces of a polysurface Tweet

[roy_orengo]

Hi all,
I'm not able to set different materials on each surface of a poly-surface. With Rhino render and Raytracing (Cycles) rendering it works fine, but in Octane I can see only one material for the entire poly-surface.
What steps must I do?
Thanks,
Roy

Can you please send me a mesh that demonstrates this problem Roy.
