About Rendering Quality

[LeeHanmin]

Hello, this is really a nice job.
But when I used 4D-gaussian to render the interp/aleks-teapot in the hypernerf dataset yesterday, I found that the rendering quality was poor. There were obvious mold penetrations in the hands and dynamic areas, and the modeling was insufficient, which was inconsistent with the results of the paper. What causes it?

sry, we didn't perform the rendering results in this dataset (You can see the paper). And We also found that 4D Gaussians indeed cannot handle well in this scene. And we are working hard to find the reason to solve the problem.
It probably maybe the motion part didn't exists in point clouds initialization.
