im playing this hogwarts legacy but it has over-the-shoulder third person camera view, in which i will get dizzy after playing for more than 10 minutes.

i was wondering how can i use cheat engine in general to mod it to centered 3rd person camera view?

Find the camera entity structure and the player entity structure, see if the camera entity has an instruction that only writes its coordinates and orientation. If so, use that, if not use the instruction that writes every entity's coordinates. Then when writing the camera entity's coordinates and orientation reference the player's and write that instead. You will have to test different Z values to get the best height and may have to put the camera slightly in front of the actual coordinates based on whether the game tries to draw the player over the camera.

Explore all three and more, I'm sure if you google it someone has made the meaning more clear. It's possible that first person view is a default option from some combination of those.

If all else fails, do it the harder way I described above.

Odds are matinecam is all about cutscenes and making the camera follow a path, so possibly ignore it. Springarm settings likely affect how the camera will react when the field of view is obstructed, so another ignore but may offer fine tuning.

Is third person camera a float? Try setting it to 0,1, or some value between. Maybe even experiment with -1 or -2. If it is a byte, try FF. Don't discount that there may be yet another camera related setting that enables first person view.

I'd look but I don't really want to buy the game and it's going to be a while before it gets cracked.

I honestly think you will be able to solve it in less than two hours doing the methodology I described in my first response because even though you are doing it for the first time, those steps are relatively easy to follow.

I talked about something similar in this post:

The first steps of figuring out the entity structure will help you along. You can stop at the player and camera if it is the same structure or code a number of solutions from there based on what you find.

Not too long ago I was trying to center the player/camera view just like you are in the game Friday the 13th, which is also a UE game.

I remember I was able to find the camera coordinates and disable the instruction that wrote to them, so when I moved my character, the character would move around WITHOUT the camera following it. Sadly, I wasn't ever able to figure out how to actually center the moving camera.

Not sure if this will help, but the way I found that coordinate was by using the in game console command: FOV (field of view)

When I would input fov 50 I'd do a CE scan for a float value of 50, then I'd enter fov 100 and rescan for 100, and so on... and that's how I found the fov address. Browse this memory region, and convert view to float, and a little later I could see the camera xyz coordinates very close to the fov address.

If you happen to get the player centered in camera, please share what the solution was because it's probably very similar since both games are UE4 I believe.

After spending some time with the game, the camera is a springarm camera which resides mostly in the XMM registers.

To find it, I walked the character to a wall and searched increased and decreased values based on how close and far away the camera was from the player.

The value is a float between 10 and 400.

Once found, I looked in the structure, but most values there crashed the game when altered. Then I looked at the other xmm registers and found the X, Y, Z coordinates, and a height modifier.

Because orientation matters, I ignored the X, Y, Z coordinates and just added some height to the camera.

Setting the springarm distance to 0 and height to 30 into the xmm registers at the appropriate places, the camera almost always stays in a natural first person view.

Unfortunately, fresh out of a cutscene or battle the camera code doesn't work, so you need to reclip it. I never looked for anywhere else in the code the camera might reside to affect it when it hasn't clipped. If you found that, and also had the springarm values written there, it very likely would resolve this issue. Otherwise, when the camera stops reverting to first person mode, angle it to hit a wall and it will work again.

Another interesting thing about the game is the code is in the same location every time, so you don't have to use AOB injection to edit it. I still did out of habit.
