How can I compress my FBX file further below 5MB?
I have an .fbx file that takes 58.8MB
After converting it to a .glb using draco compression with this package:
https://github.com/facebookincubator/FBX2glTF/tree/master/npm
The file now takes 28.4MB
Ideally, I would need to get the file below 5MB.
How can I achieve that ?
I am using 3DS Max.
The character used to take the whole screen on load, now here is what I see after converting the .fbx to .glTF, reducing the size of the textures from 2048x2048 to 1024x1024 and converting them to .jpg :

To reduce the filesize of a model you’ll first need to know why it is the size it is. Often this is textures, mesh geometry, or animation data. If you export to .gltf instead of the binary .glb you should see textures in separate files, and geometry and animations (if any) in a .bin file.
To reduce the size of textures, you’ll want to use traditional image optimization tools and shouldn’t need to edit the glTF file at all.
To reduce mesh complexity, use a modeling tool (e.g. “Decimate” in Blender), or compress the glTF file using Draco (as you’ve done here). Reducing the size of animation is a more advanced topic.
