How to convert the cuda-based npz model to npz used in web demo ?

[bruinxiong]

I trained nerf-sh model with chair dataset. After extraction and optimization, I got the tree_opt.npz. However, I loaded this npz with webgl viewer, I got an incorrect viewing result as follows:

If I launch this npz with cuda-based volrend viewer, I get correct viewing result.
Furthermore, I downloaded the uncompressed NeRF-synthetic files used for the web demo, the npz file is ok when I load with webgl viewer. So, I have a question. Is there any difference between the tree_opt.npz and you provided uncompressed npz model ?
