Long time since i posted here (sorry), anyhow as the quadmesher in Moi will not give you continous edges across a model, ie a good edgeflow upon export perhaps the automatic quadmesher this researchpaper introduces would solve the problem for Moi as it can create nice smooth and very natural edgeflows on the models. I'm sure something clever could be extrapolated from this paper and implemented into Moi. :)

Permission to use this researchpaper data can be obtained by contacting the author, it's free of charge to use their findings. :)

(the author of 3D-Coat is most likely planning on implementing this automatic quadmesher solution too)
