Included examples of both 3D spotting from myself or teammates showing enemy players through walls, objects, things that can't be destroyed and there are examples of passive/reticle/nametag spotting where no input is made by myself or another player but because my reticle/crosshair was near an enemy they are 3D spotted automatically from my perspective. To be clear this has been a problem going back to Battlefield games that have been developed on the Frostbite engine mainly starting with BC2. Yes BF3, BF4, BFH, BF1, and BFV had these kinds of issues with occlusion culling and I've pointed it out a few times over the years in most of those games ( often times in Random + WTF videos like I do with most bugs ). The point being it's clear that it is impossible for DICE to make 3D spotting balanced or perfect to where it never gives a player free wallhacks so stop putting it in the game and try to correct the issues from other directions. Is it a player visibility issue? Change the lighting, shadows, remove the lens/optical flares, UI clutter taking up screen real estate or lower the textures of the maps, terrain, etc. whatever is needed. Is it because people have trouble seeing prone players or identifying whether it's a prone player or a dead body? Remove prone from the game, it worked great in BC2 and it didn't stop bushwookies from...well being in bushes.
The Q/button spot is one thing, it requires player interaction but that spot also shows up for every other player on your team and requires no input or action from them to get. So all those times you felt like you got randomed from across the map by someone who wasn't originally shooting at you, yeah that is often times why. However the passive/reticle spotting requires no direct interaction other than getting your reticle near an enemy and it works up to 50 meters. It was a problem in BFV when they bumped it up to 25 meters so having it go all the way out to 50 is far worse and just adds to the confusion. Was I spotted? Was it a drone? Was it dumb luck with passive spotting? It's why I don't think a notification of "YOU ARE SPOTTED" would be enough since there are multiple types of spotting.
3D spotting used to be something that enforced the rock-paper-scissors aspect of Battlefield at least up to Battlefield 2. In that game jets, choppers, tanks could only see other vehicles and anti-vehicle stations in their HUD which meant they had to be in first person view and it meant they were more likely to focus those targets ( bombers focusing AA stations, ground vehicles instead of infantry ) meaning vehicles would be focusing other vehicles and not just infantry the entire round.
mus1ck's idea for the video title, all of my ideas for it were way too long like "DICE Please Stop Forcing 3D Spotting into Battlefield"
Why bring this topic up again? Because it continues to feel like DICE is training players to look for and aim at 3D doritos/diamonds/whatever above a player's head and not the players or player models. They can't seem to let players adapt and learn to look for themselves they always seem to fall back to holding the player's hand too quickly.
Oh and yeah I know it's not technically "wallhacks" but trying to explain that and the difference between what it originally meant and things like ESP would be a pointless tangent for the video topic.
