You can use my convertor for doing this.
TpFMC
Some points:
use tpfmc.exe the console convertor is more handy
export with ASE format, with following params:
New into TPF addons
The object coordinate is based on local pivot, not the world space (if you use the windowed converter, it's world coordinate), so you if have scaled/mirrored the object please reset the pivot to get the correct size. You can rotate the pivot.
You need to assign smooth group to all surfaces to prevent normal abnormal.
The convertor supports UV0 and UV1, the material name with subfix in 3dsmax will be the material name in the output file. Each object in 3dsmax scene result one msh/blob pair, so you can "export" or "export selected" by once then start the conversion of all by once.
Normally it will work correctly, I have only issue with tangent and bi-normal with ASE format, but in most cases it won't have effect on your result.
The only drawback is this convertor doesn't support animations so far.
The convertor from BR146 has some normals issue from my observation, other than that, you need to export objects in seperated obj files, which may be not so pleasant to use if you have a great quantity of object to convert
