Yo people, I recently found out a way to import Blender models in OoT without using MilkShape3D or Wings3D.
The way I did it is pretty simple.
Make your Model in Blender. Export it as a .dae format. In the settings of the export, uncheck "Triangulate" and check "Include Material Textures" Open Sketchup and Import the .dae model you just exported. Place it, resize it, kill it, do whatever you want. Export as .obj and enjoy the result!
Hope that this will help many people.
As a proof, here's some pictures :
Thanks to Originalink for the model.
