Looping/Array Help

Yeah, thats about right. For every mat id you need to search your Array for that mat id and add it only if it dosent exist.
Alternatively you can use or use appendIfUnique() or just add all of them then run makeUniqueArray() on the array (AVG or Max 2008+ only)

Thank you - I have found the functions I think i need, I am mainly for the moment stuck on compiling the logic together...will it be a combination of If, If else statements combined with for loops...

Currently I cant get my head around what it requierd. I can create the for loops to reutrn faces etc...but to get a for loop to search each face for a MTL ID # and then add the value to an array - this is the first step I am currently finding difficult, I hope to manage ok with the rest.

Thanks

This code asumes you have 1 object selected and it's a editable poly:


usedMatIDs = #() -- initial cleared array
for i = 1 to $.numfaces do appendIfUnique usedMatIDs ($.GetFaceMaterial i) -- the loop
sort usedMatIDs -- sort by number
print usedMatIDs.count -- print number of unique mat Id's

Thanks for the code snippet - i am looking forward to seeing the results...the code seems a lot more simplified than i imagined.

Thanks for the help.

ok I had a little play will be having a more detailed test after dinner. I seen this in your script and I never seen it before and when searching maxscript reference I could not see it - the only one I know of is:

polyop.getNumFaces

Is 'numfaces' a shorthand version? --(Nevermind found it)

Why did u choose numfaces instead of polyop.getNumFaces

Also GetFaceMaterial is something I was looking for but never found it - i now have the reference thanks for this.
