Decided to tackle this asset again and redo the textures and materials. It's starting to progress a bit but I'd imagine would benefit from a proper layered material system like in UE4. Trickier in UE3.
I've had some time away from Heavy Gear Assault and have tried to keep busy (interesting going back to UDK for these assets after playing with UE4 on Heavy Gear). Comments more than welcome! Renders snagged in UDK.
