A quick test of OurBricks (see Gaiiden post about this) with the alien. I will have to see why the smoothing is not exported but it is working really well (it took me longer to find how to embed it into this post than exporting the model and uploading it on the OurBricks site... I was pasting the "embed" link instead of the "link to this model" one).
edit: I opened my eyes and discovered the "export normals" checkbox in the OBJ export in blender. I tried it with my Minotaur...
