A physically based lighting model is planned for the initial release :)

Does this still happen in 0.11b?


Edit: Great! Thanks for checking :)

This is most likely the same issue that happened when you open Unity when you had closed SF with it. The "solution" was to detect when the error happened and close the window, so I suspect that's what's happening here. I think it would take time to get that fixed, but the errors of this topic is fixed by that, so I'll mark it as complete :)

Does it still happen in alpha 0.11?
