another gl morphing topic

Dec 27 2012 | 1:44 pm

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 , using xfade .
quite a classic on this forum , i know , but ….
here is a simple patch ,
at its simplest :

-- Pasted Max Patch, click to expand. --

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 …

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 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 …

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

is this possible to use 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 ?
