Hey Gleb I beleive this is a problem to do with object culling - the frustum clipping class culls while objects by detecting whether their bounding spheres are visible within the view - and for that to function correctly, the bounding dimensions of each object have to be correctly caclulated. Sounds like this isn't happening for Sprite3D
I'll look into the problem, but in the meantime you should be able to turn off object culling on the clipping class: myFrustumClipping.objectCulling = false; and to help keep this bug alive, you can submit a report to the issues list on googlecode: http://code.google.com/p/away3d/issues/list this has been growing a little in recent months, but i'm finally getting a chance to have a look at the outstanding bugs cheers!
