View Full Version : Change a model during animation..is this possible?

04-18-2012, 05:00 PM
Hey LW'ers,

I need to break one of the rules I have never broken before. My character's animation is half done but I need to change and add to the model. Is there a way to do this without loosing the time spent on the animation?
Is it possible to add geometry to the original model, weight map it, save it as a new object, setup the proper bones and hierarchy, and then replace the object without issue? (Ideally keeping the animation but having the new geometry and rig work)

I have tried a couple times but get "Error: object loading failed".

Is this possible or is this destined to tangle things up?

Thanks in advance!

You should be able to do what you want. What if you just load the object into a clean Layout. Make sure your new object is fine.

I've never tried it, but "saving the rig" gets tossed around, so maybe you can at least salvage the skeleton.

Ok, the object now loads without the error message..forgot about the skelegons in the objects layer. So it should be just a matter of setting up the bones.
Thank you for the help so far.

Another option would be to go back to a scene where it's just the rig (hopefully you have one), swap out your object, add whatever bones and rig controls that you need.

Go to your file that has the animation and save out the motions of your animation.

Then load those motions onto the new rig. MotionCycleGN (v.2.0) is a handy lscript to do this.

Adjusting a rig once you've animated is possible, it's just a headache.

What kind of changes would destroy the utility of the original model?

I'm referring more to adjusting/adding to the skeleton. The model should be fine.

OP= original poster.

s/he seemed to think that the planned alterations would make the model unusable for that animation.

nothing to it... just make whatever alterations to your object, weight accordingly and it'll still work fine. The only time you get problems like this is if you go changing proportions, limb lengths, etc, then ur screwed.
