Another update on my progress
It now handles MPD, transparency and fake seams.
I also seem to have indirectly solved the material binding problem as a result of using a different approach which was needed to preserve the LDraw recursion (submodels) inside the export file.
Lighting is still a bit overexposed haven't really played with lighting in blender nor the collada file itself.
Still need a lot of tweaks and cleanup as the whole process is still very fragile (e.g. mpd's using embedded parts won't export correctly).
I'm still hoping to find someone willing to help me with the collada materials etc.
