How to reduce the size of any FBX file exported from maya?

[saadaziz887]

When I exported an FBX file from Unity its size was 41 mb, but when I imported the same file in MAYA and then without changing anything I exported that file again in FBX from MAYA. Now its size increased from 41 mb to 60 mb.
My questions are:
1. Why its size increased from 41mb to 60mb after exporting it from MAYA?
2. As this file's textures size is only 10mb, but over all its size is 60 mb, so in short, how to reduce its size?

FBX can be ASCII or binary type, and the latter are smaller than the former. This also might in-/exclude datasets that specific exporter supports, i.e. same content exported as FBX from Maya and Blender might differ.

The file size is also dependent on whether you embed media i.e. textures; when disabled, textures are saved separately, smaller FBX file.

Everything contributes to the file size - consider deleting unnecessary uvsets and optimize the geo, decrease textures size and color depth where possible. Turn on Display > HeadsUpDisplay > PolyCount to see how much is each object.

Just a guess, in your image we see the size of the images in the current folder, however this doesn't count those 5  sub-folders - could be same +10megs, so you end up with 60mb.

Otherwise, can't be told more without seeing the Unity FBX file itself. Share it, if you want more specific input.
