Game engine requires single UV channel, but body has two

Hey all, I'm trying to figure out a little hiccup I ran into while importing the iClone characters into Lumberyard.
Lumberyard can only ingest materials with a single UV channel, but the body of the character comes out with two, so if I only use one (deleting one in Maya), I end up missing some textures in the game. Has anyone run into this issue, with Lumberyard or any other game engine, and if so, how did you solve it?
Thanks!

When you export your FBX be sure to set it to multi-materials, otherwise you wont be able to configure all the materials in the material editor. As i understood it, Lumberyard is set for AAA games, so typically a single character will be... well big. You can achieve optimisation with LODs (instaLOD), but it requires a bit of modifications of the fbx settings and of the materials on each LOD level. For now that's how i get it, ican be wrong.

Hey Alex,
I'd follow the game engines protocol. Send it (1) uv channel and (1) texture map.

Example:
This characters has (14) uv channels.

Unwrap it to have (1) uv channel.

...and (1) texture map.
