VR Expansion Plugin

Something that Half-Life: Alyx does is, they allow the VR camera to interpenetrate objects from head movement, but not walking or teleporting.

For example: If the player is up against the wall and presses the analog stick to move in the direction of the wall, they won’t move. If they put their head into the wall, then their vision will turn orange.

The way that seems to work is

1. Navmesh (analog stick) movement will move the players camera, but not into walls.
2. The player’s navmesh position is constantly updated to match the position of their camera after applying navmesh and playspace movement, while their camera is not interpenetrating objects.
3. If a player’s camera starts interpenetrating objects, their navmesh position stays at the last good position, and their vision turns orange.
4. If the player tries navmesh movement while their camera is interpenetrating geometry, their camera is re-positioned back at the last good position and their vision returns to normal.
5. As a result of 4, the player camera cannot intersect with geometry while using navmesh movement.

seems to be an overall comfortable approach.

Is something like possible with plugin? If so, how would one go about implementing it?

Set bUseWalkingCollision override in the settings and assign a set of custom collision settings for it. will be the collision settings used when not locomoting, and when locomotion IS running it will use the standard collision settings. Then handle your blinders however you wish with a camera collision body.

I’ll note that in general keeping pushback but darkening the screen during it is the same effect as valves, but doesn’t require handling depenetration angles, their solution is rather lacking actually as you can clip through walls and blind interact with things.
