Need help with sapling mode from blender exporting to ue4!

Hey guys please help ,umm so i usually export trees made with blender with sapling mode and… when i export them i can only edit the entire tree but i need to edit separate textures like the leafs and trunk and

do you have different ‘materials’ (in blender) for each item (leaves, trunk)…

btw… how well do the blender trees work in ue4, do you get movement (i haven’t tried blender trees yet)…
