Hi Eric,

Would setting the individual matrices that make up the global view
matrix fix it for you? When rendering many (aligned) trajectories
independently, I will find a view I like, and then render it over and
over again across all the different molecules I have loaded. Here is an
example from one of my rendering runs:

foreach mid [molinfo list] {
#Set the view to be consistent for all molecules.
molinfo $mid set rotate_matrix {{{0.992137 -0.12383 -0.0181618 0}
{0.0190481 0.00597697 0.999806 0} {-0.123696 -0.99229 0.0082886 0} {0 0
0 1}}}
molinfo $mid set center_matrix {{{1 0 0 -0.590847} {0 1 0 0.0511168} {0
0 1 0.162233} {0 0 0 1}}}
molinfo $mid set scale_matrix {{{0.0376508 0 0 0} {0 0.0376508 0 0} {0 0
0.0376508 0} {0 0 0 1}}}
}
Does that do what you want?
