I’m trying to implement First Person Shooter camera. FPS camera is something that stays around the forehead of the character model (and bone) (track the head’s position and move together), and it rotates as the head rotates. Or I should say that the head follows the rotation of the FPS camera. (In this case, the model keeps standing and only rotates its head to see the world around him). I thought of using Universal Camera and a Bone that is embedded in the head mesh, and synchronize rotations of these two. But I am not sure which properties of camera and bone should be linked. And axis (local or world?) matter is also confusing. I’m using a model (and texture) from this example. This Multi View method would help you to compare TPS and FPS. If you could help me I really appreciate it! Thank you for reading. miyabi

Hey I am sorry for being late, but I implemented what I wanted to do. Here is the result playground. What do you think?

Wow this looks great! This dynamic fov control must be very useful when you move around the world, but in my case, models just sit and only move their upper body to see the world around them, so I might not employ your great method to my app. But thanks for showing me pretty good demo! :grinning:

What I wanna do looks like this playground. Is there any better way to do this? Thanks for your attention.

It looks great I think you should go with it

Offset the local position of the camera forward so that the view does not feel like it is in the head of the model, or hide the head (don’t know if this is possible).

That is exactly what I am trying to solve. I think, to properly make the camera stay exactly the same position relative to the head (maybe on the forehead of the model), the camera need to move inside the local space of the head (actually the neck bone). So I want the camera to use the local space of neck bone as its world space.

You know the complicated thing is this, I want the bone to follow the rotation of the camera and I want the camera to follow the position of the bone (and also move some distance relative to the local space of the bone)

What why? That is not normally how you would do it but ok… Why do you need the camera attached to the mesh and not vice versa? Am I missing something?

I thought, it is said that I can control universal camera by mouse, so if the bone follow the motion of the camera, that would be good.

Maybe the best solution is Parent the bone to the camera, and somehow implement some code to move the bone from mouse.

Not necessarily, in fact it might cause jittery jumpy movements, and you are gonna have to constantly update your up vector anyways on the camera. Re read my post about the height and animations reliant on basic math. A simple solution given what you would want to lerp the cameras position to the bones absolute position. But then you are gonna have to figure out a way to establish forward.
