[xoreos-devel] KotOR animations

[Vsevolod Kremianskii]

Starting from scratch it is then :) I remember successfully getting KotOR
animations into Blender using MDLops in the past. And since the source code
for that is readily available (it's a Perl program), I figured it shouldn't
be that much of a hassle.
