[T5][T6] Player camera position leads to improper view angles when using lean

[crealte]

What happened?

Based on what I have found so far, the default player camera model is positioned slightly to the right of the player center. Therefore when the player leans right, only a small part of their player model is visible and when the player leans left a large part of their player model is visible. This can create unfair gameplay advantages when a player leans to the right while behind cover giving them a clear line of sight while being largely concealed to others. And likewise leaning left proves to be a disadvantage.

While the simple solution is to disable lean with the newly fixed 'allowlean' dvar, it disables one of the core movement mechanics of Call of Duty PC titles. Even without lean, the minor camera offset will provide a similar advantage when players peak corners from the right vs the left because they will see the opposing player before they themselves can be seen. And likewise a disadvantage when peaking from the left.

Expected result

In Call of Duty 4: Modern Warfare the camera position is not off-center so when players lean right or left, there is little to no discrepancy between what the player can see vs what other players can see.

this is an animation issue, we dont have plans on fixing this, like you said, you can disable leaning, or make a mod that imports the iw3 player movement animations to fix this issue

would a dvar such as bg_leanAmount work for this? it will basically offset the camera by the dvar's amount

Is that a dvar I can test with? We tested with some existing dvars but nothing that really addressed the issue (I can dig them up if helpful). My suspicion was that even beyond the animation of lean, the player's camera is slightly off-center to the right. so it's the compounding effect of both the default camera position and the animations so even with importing iw3 player movement models it still would be off unless there was a way to change the players camera position?

Adding a few photos that I hope visualizes it, where you can always see more while showing less when peeking to the right.

I guess to summarize what I'm asking for, is there a possibility to get some sort of dvar to adjust the camera position?

[ineedbots]

no, but the dvar bg_leanAmount was just added to staging

[ineedbots]

the point at which the camera is, is the same across all call of dutys, its always at the origin + view height, the lean just adds +- 20 units. its the model/animation difference that causes this issue

[ineedbots]

the bg_leanAmount was added in the latest update today
