That explains why I keep getting blown up by invisible R/E's. I make sure I look all over the objective before hacking, but there it goes, I'm dead two seconds later by an R/E.

My buddies said that people keep putting them outside the objective, but I check there, too. Yet, I still get blown up.

Been trying to find a way to really hide RE for nine months now but AFAIK there's no way to make them disappear.
They always bounce from 3D model of structure.
Sure, they can be hard to find, but still findable.

Well, I don't say there's no way on earth, but it's likely there's no invisible RE's.

There's no truly invisible REs.

There are places where they "clip" inside objects and only the tiniest part of the explosive is visible, but even then, they CAN be found.

Part of the problem is that you need someone looking at the RE for a good few seconds before it's lit up and revealed, or you need to stay well within scan range for san amount of time determined by your suit's Scan Precision. Scouts are the best hunters of explosives, and I hope Active Scanners will help to light them up for other suits.

That doesn't mean there doesn't need to be a fix, because some placements can make the REs far less visible than they should be.
