Best way to reduce size of FBX files?

I'm working on optimizing my current game project and the biggest things seem to be animations and fbx files. I'm using Legacy animation. What's the best way to reduce this footprint in the game download and memory size? Should I remove / delete the animations that I'm not using? If so, do I just remove them from the list of animations or do I have to actually delete them? Also, if I use a tool like Cruncher to reduce the polygon count of an FBX file, does that also reduce the size of the related game object in RAM and in the size of the final build?

 

Reducing polycount will bring down the RAM footprint. If you use Mecanim there is an optimize button that will remove extraneous bones from the rig and you will not have to load the retargeted animations meshes either.

 

Cool ... thanks. I'll definitely go through and do some heavy polygon reduction. I'm using Legacy unfortunately. I did try and delete some unused animations from the FBX and that seemed to have a good result. So I'll do both polygon crunching and deleting animations and see how that goes.

Do you know if there's any way in Unity to have it convert all wav files to MPEG or change all of them to "Stream from Disc" rather than load into memory? Changing that option one at a time is really painful.

 

I think you can multi-select and hit the buttons for whatever.

 

nope ... unfortunately mult-select is enabled for audio file settings.
