Hello peeps,
Something seems to be wrong with the Motion Blur and the Interactive Renderer.
If you turn on MB and then tweak the corona camera tag settings it stops working and you need to disable and then enable it again in the render settings to update - Otherwise it just doesn't do MB anymore. It literally ignores the fact that MB is turned on.
Seems like a crucial bug that is also present in Corona 4 Hotfix 1. Would be cool to consider another hotfix I guess?
