Yes, Varian and Irene, I created the structure with Vue primitives... even if it's empressive, there's really nothing hard to do... it's two boolean operations repeted :-) Irene, you choosed the best : Vue for creating some amazing scenes, and renderosity's forums for sharing your creations, questions, discoveries, etc... Hope we'll soon have a look to your first images ! Thanks Jarm ! PS : It's not Traveller's wings... I can't remember where I downloaded it, but I'm sure it's not Traveller's.
