Yaw/Pitch Issues with Head Rotation + Pixelation

[toobawaqar]

I used the plugin and created a Gaussian Splats asset and added a .ply but the issue is that the splats seems to be stuck to the viewport when I move my head on the user relative Z axis. The video is attached, also the splats seem to be backed by a lot of additional pixelation in VR view, is there an issue with stereo rendering?

To add, the output is very laggy, swift movements cause the black screen to follow which one sees in high lag scenarios.

I am using PICO 4 Ultra
