pls help! Dummy/Helper animated on spline needs xyz Keys!!!!!
Hi all,
i am desperate! I have a dummy/helper animated over a spline. So there are two keys 0 and 100 percent on the spline. As i want to import that Dummy to Eyon Fusion (there is a camera attached) via FBX i guess i need to convert the animation to xyz coordinates in space. Because Fusion does not get the ani that is defined by the spline!
Is there some script or hidden tool in Max that will do that conversion?
Or is it a simple import/export failure that comes with FBX?
please pretty please i need that clue! :-)
all the best,
Michael

perfect! thanks!

from a quick glance a find
from a quick glance a find one miss in the script.
if you do this:
-----
(
$.rotation.controller = Euler_XYZ ()
$.pos.controller = Position_XYZ ()
)
---
then max will reset the position controller for the current selection, ALL objects initially selected. Do you want that?
$ is a symbol for the current selection.
you should probably comment out that line...
if you want to change the controller on the original bone then you could reach it in this script by typing:
-------
item.rotation.controller = Euler_XYZ ()
item.pos.controller = Position_XYZ ()

OK that execute helped big
OK that execute helped big time. I'm sooo close! But if I run the script below there are no errors. But the bones go wacky. HOWEVER. if I only select one bone at a time it works. I'm trying to figure out why. Maybe you see something.
--begin script
select # (
$Bone_Shoulder_Left_SK
, $Bone_ArmTwist_Left_SK
, $Bone_Arm_Left_SK
, $Bone_Elbow_Left_SK
, $Bone_ElbowTwist_Left_SK
, $Bone_Hand_Left_SK
)
myObjectsArray =selection as array
startFrame = 0
endFrame = 20
byFrame = 5
for item in myObjectsArray do
(
newObj = copy item
--newObj.controller = PRS()
newObj.rotation.controller = Euler_XYZ ()
newObj.pos.controller = Position_XYZ ()
newObj.name += "_Bakeanim"
newObj.parent = undefined
for i = startFrame to endFrame by byFrame do
(
with animate on
(
at time i newObj.transform = item.transform
)
)
(
--$.controller = PRS()
$.rotation.controller = Euler_XYZ ()
$.pos.controller = Position_XYZ ()
)
myBakeObj = execute ("$" + item.name + "01_Bakeanim")
(
for i = startFrame to endFrame by byFrame do
(
with animate on
(
at time i item.transform = myBakeObj.transform
--at time i item.transform = $(item.name + "01_Bakeanim.transform" )
)
)
)
)
--END script
just saw a thing you need to
just saw a thing you need to fix.
If you need to construct a link to an existing object there is sometimes a need to use the execute command.
so your script has this row:
-----
at time i item.transform = (item.name + "01_Bakeanim.transform" )
------
change to:
------ start script
myBakeObj = execute ("$" + item.name + "01_Bakeanim")
at time i item.transform = myBakeObj.transform
-------
this should work better. There is one problem with this and that is if there exist two objects with the SAME NAME... then 3dsmax chooses the first one (in its own order).

Hmm the trajectories is only
Hmm the trajectories is only the position of the objects it wont include any rotations. I guess you mean the collapse transform feature.
Could you please explain what you are trying to do since a copy of the bones doesn´t work.

yes collapse transform..
yes collapse transform.. sorry for the misinformation.
My goal is to "bake" keys into a skinned skeleton so that I can delete all control objects such as ik controllers, spline controllers, wire parameters, etc. This way I can cleanly export a clean and organized bone hierarchy and it's mesh to a game engine. The game engine wont recognize all those controllers. Does that make sense.
I have a good path.. I'm just not familiar with maxscript syntax etc.. I very proficient in MEL. sigh
--BEGIN
myObjectsArray =selection as array
startFrame = 0
endFrame = 100
byFrame = 1 --set a keyframe for every frame
for item in myObjectsArray do
(
newObj = copy item
newObj.controller = PRS()
newObj.name += "_Bakeanim"
newObj.parent = undefined
for i = startFrame to endFrame by byFrame do
(
with animate on
(
at time i newObj.transform = item.transform
)
)
)
--EVERYTHING ABOVE WORKS GREAT
--This next part is where it all goes bad
myObjectsArray =selection as array
startFrame = 0
endFrame = 100
byFrame = 1 --set a keyframe for every frame
for item in myObjectsArray do
(
for i = startFrame to endFrame by byFrame do
(
with animate on
(
at time i item.transform = (item.name + "01_Bakeanim.transform" )
)
)
)
--END
the feed back of the second part says:
-- Error occurred in i loop
-- Frame:
-- i: 0
-- called in item loop
-- Frame:
-- item: $Bone_FootToes_Left_SK
-- Unable to convert: "Bone_FootToes_Left_SK01_Bakeanim.transform" to type: Matrix
So it is not associating the variable's name of Sequence_Node_SK01_Bakeanim with the obj of the same name (which does exist in this file.)
This is close to what I
This is close to what I want.. but now all I have to do is get the keys back onto the original.. sigh.. I wonder why I can't just write a script that selects my bones and collapses the trajectories. If max can do it, why can't it be scripted. Thanks again.
Ok I did a new version that
Ok I did a new version that should include the rotation as well. But I still need to make a copy of the original object and "collapse" the animation there. The reason is if their exist any linkage between the selected objects then the childrens positions are dependent on their parent position. And if I remove the IK link controller (if this bone object has that) then its childrens animations will be wrongly positioned.
So instead I make a copy of the selected objects and bake the animation on them. I then have a question in the end that asks if you want to delete your original objects!
PLEASE SAVE your maxfile BEFORE trying this. I am pretty sure you want to keep your original scene before baking the animation instead of the baked endresult. Especially if you need to change something.

actually I figured it out..
actually I figured it out.. that is with your original guidance. Thanks. I wanted to automate a similar function to collapsing trajectories.. here is what I have to so far, thanks for your help!
