I’m trying to write a script that will handle the assembly of several boned and keyframed objects into a single object, for export into a game engine. Alas, for it is not working!
What I’m trying to do is copy the objects to a final master-object one at a time, adding their bones to the final object’s skin list in sequence, and weighting each new vertex in the final object rigidly to the bone that has just been added. A better, more sophisticated script would preserve bone weights, but what I’m doing is all rigid (object shattering as skeleton animation).
The result, unfortunately, seems to be bones that are weighted rigidly based on the original envelope weights. I’m not really sure why that is. Any assistance would be greatly appreciated.
--Initialize
clearlistener()
--This assumes the existence of a series of skinned and keyframed objects called Outgoing_1, Outgoing_2... Outgoing_n
Incoming = $*Outgoing* as array
j=0
--I've been trying to run this several times in succesion, so I get rid of the last attempt here
delete $*FC*
delete $*Final
delete $*Final_component
Final_Component=editable_mesh()
Final=editable_mesh()
Final.name="Final"
addmodifier final (Skin())
select final
finalskin =$.modifiers[#skin]
--Main Loop
for i in Incoming do (
--Track iterations
j=j+1
--Get the number of verts in Final
oldVerts = getNumVerts Final
--Get the name of the bone of i as iBoneName
select i
iSkin = $.modifiers["skin"]
SetCommandPanelTaskMode mode:#modify
iBoneName= Skinops.GetBoneName iSkin 1 1
--Attach copy i to Final
select i
Final_Component= copy i
Final_Component.name= "FC"+j as string
select Final_Component
attach Final Final_Component
-- Get the number of verts in Final
newVerts = getNumVerts Final
--Add i the bone of i to final skin bone list
select final
skinOps.addBone finalSkin (GetNodeByName(iBoneName)) 1
--skin vert 100% to bone j
--for oldverts to newverts in final
for VertexNumber = (oldVerts+1) to newVerts do (
--Get ready to do a skinop
select final
modpanel.setCurrentObject finalSkin
--Set Vert to Rigid
skinOps.rigidVertex finalSkin VertexNumber true
--Skin Viert 100% to bone number j
--I /think/ this is what's going wrong.
skinOps.SetVertexWeights finalSkin VertexNumber j 1.0
)
)
Failing this, is there a more elegant way to combine several meshes into one object, without losing keyframe and skinning information?
