Yes, those sorts of things. Very hard to pull that stuff off
with skeletal animation.
That's a good example of what I meant by "depends on how well they
import". This kind of stuff is actually well suited for bones/
hooks in most 3D animation apps, but many games don't support bone
scaling
scaling I have done.
weighting is currently beyond my skills.
Perhaps you mis-interpreted the meaning of "weighting"... I'm not
referring to any sort of soft-body dynamic, it's just the term used
in some animation apps when you adjust a bone's influence on any
given vertex.
Example: You got bone A, attached to vertices V1, V2 and V3. The
weight value of V1 and V2 is 100%, and the weight of V3 is 50%. Now
say you move bone A 100 units (any direction) vertex V1 and vertex V2
will shift the full 100 units, while V3 only shifts half that.
That's a trivial example, but weighting allows you to stretch and
bend meshes more naturally than would be possible with bones whose
transformations affect their vertices at a constant 1:1 ratio.
