Thanks for the info. It only kinda makes sense right now, but I'll have to try
messing around with it a bit once I have some free time, see what I can manage.
Though I've thought of a couple more questions. Does ApplyBoneMatrixTransform
get called all the time, like every frame(but for the most part not do
anything)? And if I override it, should I call BaseClass::Apply... at the end
or beginning of the function, if at all?

Oops forgot about the code to scale. Its very simple really.
This is the function
ApplyBoneMatrixTransform( matrix3x4_t& transform )
{
float scale = sdk_grow.GetFloat();
VectorScale( transform[0], scale, transform[0] );
VectorScale( transform[1], scale, transform[1] );
VectorScale( transform[2], scale, transform[2] );
}
If you only scale certain parts of the matrix, you'll get that skewed
model
look. Can be great if you want to make a squished pancake look for
your
model. Remember it only works on non static-props.
