Dear Eric, I won’t be trolling over this issue if there wasn’t a problem with positions in UE emitter.
I understand that it works in most cases, but if you really want to tweak them to the limit, then this bug need to be solved. I have made several bugged examples using “local space” and send them over to your staffs and I’ll be willing to do so again. Just give me another email and I’ll re-create the bug using 4.5.
Best,
