Hi guys, I am starting to work with Away3D and I will have few questions in an upcoming days for those who already worked with it.

Question: Is it possible to decrease the number of polygons on the external model without editing the model in some 3D graphic software? I have bought human model made in 3D Max but it is so complex

No, you need to decimate the meshes by hand.
You can do this using multiple editors. Personally, I use the excellent Meshlab, as it decimate but does respect the original shape better than most other softs do.

You should also once done, republish the model using awd format vs 3ds for runtime use.
