It is difficult to convert from Toca 2. The process so far:
1. Open game files in Toca2 edit, convert to 3ds and ppx.
2. Import in Zmodeller 2, and quickly make a copy before the model got distorted (this took a lot of try and errors)
A lot of work to simplify and remove duplicated faces and setting matererials.
3. Then export to Sketchup to add detail and remodel some parts.
Then export to .dae and after many problems with crashes and distorted models and some experimenting with Blender and .obj files importing in 3dsimed...
4. Sending files as .gmt between 3dsimed and zmodeller 2 for editing and uv-mapping updates, flipping polygons and painting textures.
All this is quite new to me, so next project would probably not be so complicated
