Morph map just does a linear interpolation between corresponding map grid points and it requires the map sizes be the same. Also the grids of the two maps should exactly match if you want sensible results. If your maps are different sizes or the same size but the grids are not aligned you would use the "vop resample" command to interpolate one map on the grid of the other. For example,
vop resample #1 ongrid #0 model #2
vop morph #0,2
I've intended for a long time to make morph do the trilinear interpolation automatically (as done by "vop resample") if the grids didn't align or have matching sizes but have not gotten to that.

This results in a flicker in the movie with the wrong color. Any help/suggestions on how to get this set correctly? Let me know if there needs clarification - thanks!
