Description
Hi PlayCanvas
Good job on this!
I noticed that for LODs using Spherical Harmonics, each segmented meta.json file contains its own set of SH coefficients. Would it be possible to consolidate all SH coefficients and store them in just one of the model files instead?
Currently, storing them separately tends to increase the overall asset size and also makes loading and collecting the data less convenient.
Thanks for considering this suggestion!

Research direction
Start by tracing how LOD segmented meta.json files store and load Spherical Harmonics coefficients. Determine which model file could own consolidated coefficients and define the loading behavior needed to avoid duplicated data while preserving access for every LOD.
