Hello, Hope you guys doing well.
I have noticed that with some version the exported size of GLB increase significantly. A file exported in 2024-03-12 have 6.24mb but in 20250428.5 and later it has 21mb even though nothing has been changed. I also included sources of another example. Here are the comparison (I exported to all version, and kept only the one that increase sizes). Is there anything that can be done to have the same size as 2024-03-12 version?

(they all have been exported as default setting with 89 for texture quality)

@Raymon , I found the issue with size. We introduced a small bug when we did the changes to support models with more than 256 bones.

Once it gets merged you should have a new version.
