I have decided to dump using 3D World Studio (sorry Josh), I just could not get scaling correct and texturing was just wrong.
Instead, my workflow, which I have now figured out, will be DeleD for all scene creation and the Collada exporter plugin with a scale of .05 for massive models, .03 for medium sized models and .01 for normal sized models (based on how they look inside of Leadwerks),
UU3D Pro is then used for exporting to .gmf and converting all textures to .dds.
This combination works perfectly for me and also scales the textures with the models.
DeleD has a lightmapper built in.
