Sorry for asking again,
I red the documentation and all the other forum topics, but they didn't solved my problem. I'm using streamed scenes which I'm creating with:
BuildPipeline.BuildPlayer (aSelectedObjectPath, anOutputLocation, BuildTarget.WebPlayer, BuildOptions.BuildAdditionalStreamedScenes);
I'm downloading them with myWWW = new WWW (myURL); And I'm loading them with Application.LoadLevelAdditive(...).
Since Unity3 I'm getting the error: Rejected because no crossdomain.xml policy file was found.
I have the following crossdomain.xml file in the root of my local webserver (xampp):
and i can access it through my browser over http://127.0.0.1/crossdomain.xml my stream files are located e.g. in http://127.0.0.1/somefolders/oneofmystreamfiles.unity3d
In my opinion everything is as described in the documentation, but I'm always getting the "Rejected because no crossdomain.xml policy file" was found error. :(
Anyone has some further ideas? Thank you very much.
