Since RC1, 2 of my 40 scenes hard-crash Unity.

    If I try to build, Unity crashes when gets to one particular scene in my game.

    When it the editor, if I try to open that scene and see what might be the issue, Unity again, hard-crashes.

    Bug has been submitted with project to reproduce. (Case 647326)

    I'm dead in the water till it's fixed so hopefully it's an easy one!

    Did you by chance open those scenes in b21? We removed the ReferenceResolution in RC1 and if you didnt open the scene in b21 then there might not have been the auto conversion to CanvasScaller.

    I had the same issue with b21. I've just updated to RC1, and nothing yet..
    I don't know when this error occurred. I'm just creating UI and interacting with it via code.

    If this happens on RC1, I'll update here.

    I don't recall if I opened the scenes in b21. Is there any fix/workaround? Would going back to an early version and opening the scenes help?

    Kinda stuck at the moment.

    I went back to a version of my game that had never been opened in the 4.6 beta. Again, Unity crashes when I try to open that particular Scene in 4.6 RC1

    Hmm ok will have to take a look at your bug closer then. was just thinking it might have been that as i know there were hard crashes due to us removing the unused component.

    Unity 4.6 RC1 hard crashes for me, too. I opened a project that had been created in 4.6b18 (not b21) and not touched since. I created a new scene with a Canvas (screen space overlay), Text, and Image. It hard crashes when I try to play the scene in the editor.

    If I haven't yet gone to rc1 (I'm still on b20, maintaining compatibility with Unity Cloud Build). It sounds like, before I do, I will need to remove all ReferenceResolution components? Otherwise I risk crashing on open in rc1. Is that accurate?

    That interesting, a new scene should work.

    Yes or just upgrade through b21 so the auto upgrader will run replacing the ReferenceResolution with the new CanvasScaller.

    Well, I downloaded RC2, crossed my fingers, but still no luck.

    Same 2 scenes in my project still crash the app when I open them in the editor. Tried it from 2 different versions of my game.

    Pre 4.6 - Crash
    4.6 beta (pre RC) - Crash

    Not sure where to go from here. Should be repoduceable in the app I uploaded to your bug system. (Case number and link in original post above.)

    So it looks like it was a 4.5.5 change (something with convexMesh) that is causing your issue not anything to do with 4.6. It will have to wait for someone who knows what going on with that system to take a look at your bug.

    I think I found a way to work around it.

    I created a new project and brought the trouble scene into the new project. Most the components are missing but I am able to load the scene.

    I was then able, through trial and error, to figure out what specific game object was causing the issue. Had to keep deleting GO's saving scene and try loading in original project.

    The culprit is a prefab that has a mesh component with faulty mesh setting .... just says type not found or something.

    Anyway, once the bad GO is deleted I can load the scene in the original project and re-add the prefab and all seems to work.

    Not ideal, but only 2 scenes seem to have this issue so it won't be to bad to fix.

    Thanks for looking into it.
