Merci, Luxxeon!  That is good news to hear of you making content for Clara IO!

I began to use, but already discover not good.  Select edge.  Ring edge.  Loop the ring.  Not possible?  This must be kidding with us?  If I select edge ring, I can not then loop that ring select.  Already I dislike this modelling tools.  I will try the Vray with imported models only, and model with my Blender.
