Challenges
Gaussian Splat scale randomly got big
Cause: When scale attribute (v@scale) is 0, sometimes it will be replaced with other random value
Solution: Assign very small value to the scale and set Alpha attribute to 0 to make the splats disappear
Big file size
Gaussian Splats require multiple attributes to render so .ply file can be big (around 1GB per frame in this case)
Some splats are missing when trying to display large number of splats in the scene
Viewport could only display limited number of splat. If it's over the limit, some splats will disappear
