xsi level size import to unity

does unity has a scale of the size?
if you export from xsi an object as fbx how do you work to get the scaling correct

xsi has a pretty funky scaling, as of 1 = 10 cm (nobody knows what devil has driven them when setting this default)

on fbx they ask you of a scaling factor, telling that 1 = 1 cm, so setting 1 on the fbx export should be ok, as unitys default is 1=1 meter, and its default import setting is to scale imports to 0.01

a cool thing is the high of person in the first person camera, this is very usefull!

i have an object with 3 textures in xsi.
How do I get this in unity? I can export with fbx
and use the import assest. but what about the texture?
what file format of texture is good?
