@@ChalklYne -- No need to reinstall XSI ModTool. It will be compiled as a plugin for Softimage 2011, 2012, and 2015 (at least). Meshes do not have to be merged as one. You can have up to 32 different surfaces (i.e., mesh objects) in an MD3. Only one texture per mesh object. For multiple textures, on a single mesh object, you'll have to split mesh to abide by the one-per-mesh rule. LODs are exported automatically to separate LOD files. You simply append "_1" or "_2" to the names of the respective LOD objects. So all meshes (and LOD meshes) can be in a single scene. LODs will definitely help your performance. The MD3 format supports 3 levels of detail (LOD0, LOD1, LOD2... although MD3View shows them as 1,2,3). Tags are supported. All you have to do is name the tag object the full tag name (e.g. tag_driver, tag_flash, etc.) @@minilogoguy18 has created a script to create a tag.
