Script that exports the vertices of a model at each animation frame

[rpardridge]

I want a script that simply exports the selected mesh as a collada file called 1.dae, then advances one frame, exports the mesh as 2.dae, then another frame, 3.dae, etc

Any help appreciated, thanks!

Go through your timeline with for ... do cycle,
make a snapshotAsMesh() of your model,
make a new editable_mesh() and assign your snapshot to it,
select your new mesh,
export selected to <frameNumber>.dae,

delete new mesh.

Is Collada still a thing?

Try this:

with undo off (
-- create some test geometry, this needs to be replaced by you
s = sphere name:"sphere"
-- theObj should contain the object you want to export
theObj = $sphere
for t = animationRange.start to animationRange.end do (
    -- move the time slider, to make sure everything in the scene is updated
    sliderTime = t
    -- create a temp copy of the object
    local m = snapshot theObj
    select m
    -- export as frame_0000.dae, frame_0001.dae etc.
    exportFile (@"c:\tmp\frame_" + (formattedPrint (currentTime.frame as integer) format:"04d") + ".dae") #noPrompt selectedOnly:true using:DaeExporter
    -- clean up
    delete m
)
)
