Every time I build my Unity project (after adding multiple scenes) I’m getting a garbled screen. This occurs with web and local builds and on different machines. GFX card drivers are up to date, build worked fine when running a single level. Any ideas?

Does this happen on any other machine? Meaning, can you play/view this demo on another computer and if so, does the same problem occur? If you don’t have another machine handy you might post a build for folks here to try for you.
Hey HiggyB, yea our artists have tried on their systems and we’ve tried on a few non-dev systems in-house, to no avail. Web, PC and Mac builds all do the same thing. I’ve pretty much ruled out hardware. It has no issues, however, when running inside Unity.
One note, we are using VSS which has already caused many a nightmare. Could it be something with VSS?
VSS is crap but I can’t see how it would garble your screen. 
After rebuilding the project, it seems to be working fine. I’m not sure what went wrong but onward with the project.
I have had similar issues with earlier DirectX projects when assigning the device. But I’m too new to the Unity web player to understand its behind the scenes processes.
Cheers
