All that lighting is a lot of performance being chewed up by something that could be handled by texture baking. I'm doing a project where I go from a dimly lit room to a brightly lit room and I do it simply by baking textures for both states in an external 3d modeling program (3ds max) and then just swapping the textures at the appropriate time in code. Also, I could be wrong, but I thought only DirectionalLight3D worked with phong materials. If texture baking is unfamiliar to you, as it was to me a month ago, I HIGHLY suggest doing a little googling and adding it to your repetoire. Its really the best way to add "realistic" lighting to an away3d scene without tanking performance.
You could try frustum clipping to resolve your disappearing floor problem, if I am understanding it correctly. Everything I've mentioned here can be seen in action in this example: http://www.infiniteturtles.co.uk/blog/away3d-23-released. Relevant excerpts below: // adding frustum clipping is this easy clipping = new FrustumClipping({minZ:10}); view = new View3D({scene:scene, camera:camera, clipping:clipping}); On Apr 1, 11:16 pm, cwpeter <[email protected]> wrote: > Guys, I am working on my first Away3D project & I'm trying to light up > the inside of a room that is 2000x8000x8000 pixels.
