another gl morphing topic

    hi all , after many searches , without managing to understand what's wrong , what i'm missing , here's my question .
    i'm trying to morph between two jit.gl.model , using xfade . quite a classic on this forum , i know , but .... here is a simple patch , at its simplest :
    and i also join a zip file containing this same patch , and two simple objects made in blender . first object is a basic cube , second object is this same cube , with a displacement applied to an edge . it's a very basic transform , done in one time , then export obj. file . the 2 objects have the same amount of vetices, faces ...
    BUT , as you can see in the patch , they don't morph like i would like they did . faces are flying as we "xfade" , and land somewhere else on the destination mesh .
    of course i would like them to stay in place , i woud like to see the modified edge growing , as we "xfade" , and only this . (hope i'm clearly explaining)
    i think i have tried all settings i could on the render object , on the jit.gl.model objects ,on the xfade object , .... i have tried many things in blender (format files , minimum editing on mesh, ..) i have also tried to look at the obj. files in textedit (mac) , but still can't find how to make this holy grail happen !
    is the displacement the cause , even a so small and simple displacement ?
    anyway , thanks to the many people here , who 've already made me learn so much ...
    cheers Matthieu

      PFFFFFFFF
      so , after an other check ,( i think it must be the 250nth ), things work just as i want . i'm using the collada type of file (i'm sure i have tested it many times before ....) , but it's working quite perfectly , just now !
      as if i just had to post here to get it working ...
      so , now geometry is ok , the next step is the texture , ... i'm going on checks . and i'm feeling there's a kind of setting to control a "scale change" in one of the two (nearly) similar objects i'm using . don't know why , but as i xfade , the global scale seems to change . makes me think of "bounding boxes related" problem ...
      thanks for reading matthieu

      is this possible to use jit.gl.model with matrixoutput 1, to render an anim ? Apparently it doesn't work...
      Anyone would have some tips to do that ? A morphing between two animations ?
