Hi! I've been trying to port weapons from Bo1 and Mw3 into my map, but every video that i've watched uses Maya 8.5 and a "different" way to export the things into CoD5, I have maya 2012 and only the Xmodel and Xanim export tools, doenst have the options to bind, and the other things. How can I get the other "maya tool" to port weapons? Is there any other way? Thanks in advance.

[srry for bad english]

Maya 2012 is fine to port animations and guns. Infact is better.

binding is nothing to do with maya itself, its what Lime exports, you will get an MA file and a MB file, drag the MA file onto maya, (the gun) then the MB file, which will bind it
Tom has a plugin for loading tanims and joining weapon to rig, like in the tutorials. Find it on his website and install it to your maya. Also look up model plugins for it on UGX, think they are in 3rd party applications section

... you will get an MA file and a MB file, drag the MA file onto maya, (the gun) then the MB file, which will bind it...

since when??? MA is maya ascii and MB is maya binary 
 
to bind he need to drop into window file with "_BIND" @ end   

Bind file that comes with models exported, pretty sure these are just scripts that tell Maya to bind joint/s to mesh/es, so it SHOULD work with any version of Maya (they worked with 8.5, 2012 and 2014 for me).

As for porting tutorials: This tutorial by Rollonmath is pretty good and he does it with Maya 2012, so it's very relevant to you:

Just make sure when he is exporting ADS models, to ignore this, and when he converts them in Assman use the one model for all models (you'll know what I mean after watching through it).

Thanks guys!
