Hi ive got this script which works its why through multisubs. but it has a slight problem when a multisub doesnt have sequential IDs i.e. if the numbers run 1,3,4,6,7,8,10 as the missing ID's are coming back undefined, then it spits an error out because undeffined doesnt have numsubs.

fn getSubAnims theParent = (

for i = 1 to theParent.numsubs do ( --for each sub-anim

append theMats theParent[i] --add to the array and then call recursively

try(getSubAnims theParent[i].object)catch(getSubAnims theParent[i])

)--end i loop

)--end fn

i have tried putting this into the code above

if theParent == "undefined"then print "error"else

but doesnt seem to stop it.

any ideas ?

Try

fn getSubAnims theParent =
(
for i = 1 to theParent.numsubs do
(
if theParent[i] != "undefined" then
(
-- For each sub-anim
append theMats theParent[i]

-- Add to the array and then call recursively
try(getSubAnims theParent[i].object) catch(getSubAnims theParent[i])
)
) -- End i loop
) -- End fn

ok i put that back in but im getting the same error.

fn getSubAnims theParent =

(

for i = 1 to theParent.numsubs do

(

if theParent[i] != "undefined" then

(

append theMats theParent[i]-- For each sub-anim

try(getSubAnims theParent[i].object) catch(getSubAnims theParent[i])

print theParent[i]

print i

)

) -- End i loop

) -- End fn

and this is called with the following

theMats = for o in selection where o.material != undefined collect o.material

for m in theMats where

(m != undefined) do getSubAnims m --call the recursive function for each material

this is the error that im getting

>> MAXScript Rollout Handler Exception: -- Unknown property: "numsubs" in undefined <<

Ok... in fact you have to use :

if theParent == undefined then

For example and not "undefined".
