combining blender meshes for optimized draw calls in unity iphone

Ok so I have created my character in blender, and I admit that I did not create the character with optimized draw calls in mind. While creating character I separated out the different sections of model on different layers. when importing the fully rigged character into unity iphone i realized that it is taking about 20 or so draw calls just for the character! while my character is not overly complex, i don't want to have to go back and recreate the character if I don't have to.

So my question is how could I combine the parts of my character to reduce the number draw calls required? Thanks in advance for any help!

While not specific to Blender it outlines the process of reducing draw calls:

yeah i read that. Very good information in there. but while that explains what i am trying to do, it doesnt really explain how. thanks for the link though

Ok, so this never fails. i search until my eyes bleed for an answer. Then as soon as i post a question here, i end up finding what i was looking for.

in blender, to combine things into one object so that unity iphone will recognize it as only and therefore only use one draw call do this:

  1. select all object that you want to be joined (this can be across multiple layers)

  2. press "ctl+j" (all objects on different layers will be combined onto one layer)

    NOTE: I did not try this with the armature. I was nervous that it would screw up the parenting so i left it separate. If somebody who is a bit more knowledgeable can tell me if this is possible/neccessary?
