Still having trouble increasing the VR camera FOV

I am having issues of increasing the VR camera FOV.
I have refered to this post here.

How to change Field of View in VR?

In my company’s GearVR project we use a panorama background texture, wrapped to a sphere. It looks OK when the panorama scene is far away, like a typical skybox. However, we also need to support panorama backgrounds of close environments, such as the inside of a car. What happens with the default FoV setting is that everything looks grossly scaled up, and you get an unrealistic claustrophobic scene that is far from a presentable result. To fix this issue, we can normally just change the camera…

But i don’t think it gives any solution of this.

So I went to modify the projection matrix by the function Camera.SetStereoProjectionMatrix(),
it does give a wider vision but some distortion happens and the shadow of some of the object disappears. I have post a topic about this before.

Weird distortion when increase the fov of the HMDs

In order to doing some researches, I aim to increase the fov for the HMDs. The result what I want to achieve is like the result in this paper. https://dl.acm.org/doi/abs/10.1145/2628257.2628273 Here is my current environment Unity editor 2021.3.3f1 SteamVR plugin HMD: HTC Vive Pro, Oculus Rift Why I’ve done is, I get defined view frustum value from the hmd by using GetProjectionRaw(), which return the left, right, top, bottom values for each eyes’ view frustum. Then, I multiply a gain v…

So back to the question, I am still curious of how to adjust the VR camera FOV to become larger?
