Quote - Hi, you can do that with a text editor.

Make a copy of K4 .obj and replace the vertex positions with the vertex positions of M4 .obj

these lines begin with a 

v

e.g. v 0.1 0 0.2

then make a copy of m4.cr2 and link it with the new .obj you just created.

or use k4mix.cr2 and link a copy to the new .cr2, so you do not have to do the initialization again.

Ah, that sounds the easiest of all! Thanks. :)
