This simple MEL script will :
- take the name of the each mesh group (collision + mesh)
- snap it to zero world zero location
- export it as fbx (using your last export settings)
- and zero out you translations after (assuming your transformation were freezed in first place)
string $fbxPath = "C:/Users/yourname/Desktop/"; ///make sure it's / not \
///^^^type the path to files here^^^///
string $selection[] = `ls -sl`; /// List selected
for($item in $selection) {
string $fullTempPath = $fbxPath + $item ; ///create full path + name of the group
select -r $item; ///have the item selected
move -rpr 0 0 0 ; ///move to 0 position
SnapToGrid; dR_enterForSnap;
file -force -options "groups=1;ptgroups=1;materials=0;smoothing=1;normals=1" -typ "FBX export" -pr -es $fullTempPath; ///save the file
setAttr ($item +".translateZ") 0;
setAttr ($item +".translateX") 0;
setAttr ($item +".translateY") 0; /// move back to right position
}
-this way you can organize all of your repetitive meshes in one scene , laying them out anywhere on the grid.Making changes later on would be easier assuming the path of your meshes didn't change , just by clicking Reimport buttom in UE4
