Fabrice, can you confirm which OS and browser you experienced that error with. I haven't seen it on the Mac…
In terms of some more details, I am working on a blog post but here are a few items worth mentioning. The windows and sky reflections are just a CompositeMaterial that consists of an EnviroBitmapMaterial and a BitmapMaterial with transparency. It is very easy to underestimate how powerful the materials system in Away3D is, and I am hoping to see some better tutorials on the site for new users. Who should I speak to about creating some new demos to show what is possible? To construct the UV maps the tiled roof, I built a simple tool that allows for the manipulation of textures on a model in real-time. It is very ugly, and is nothing compared to the beauty of Prefab. However, it works, and I could see this functionality being very useful to Away3D users who are trying to optimize large textures being reused across one or many models. If I find some time in the next while I would like to clean this up and open-source it, but right now the code is a mess and a bit buggy. I've been so negligent in terms of getting a blog together, and will try to get on this asap. There are a dozen or so demos I have put together on things from simulating specular highlights to fake lighting. Away3D is very powerful at its core, but it is important to remember that the art of bluffing is often essential in terms of real- time 3D, especially with Flash. d On Jan 18, 5:41 pm, Fabrice3D <[email protected]> wrote: > Pitty these guys doesn't sale full houses!
