Also for those who are interested in scaling, here is a post I found in the forum from a user named GM. His account was retired, so I figure its safe to repost his explanation of scaling here.
Go to Debug and then Debug 2
add some Data under the Mesh ID
like Asset , Index
add some Keys under the Mesh ID
like ModelModifier, ModelMeshScaleRec
add some Data under the ModelMeshScaleRec Key an put their values
like
ApplyToAttachments (o=off , 1=on)
NodeName (put the bone name u want to scale)
On (1=yes , 0=no)
ScaleAbsoluteX (put here value how much u want ur bone to scale in XAxis)
ScaleAbsoluteY (put here value how much u want ur bone to scale in YAxis)
ScaleAbsoluteZ (put here value how much u want ur bone to scale in ZAxis)
Please Note that when u scale up or down any bone the parent bones also get effected. so u have to scale some parent bones too to make scale the body part in right proportion, play with different nodes and different sizes, u will get the idea
