This model is based on the 90's Optimus Prime Toy. I have modified the original design to give some length in the arms and left out some detail to keep the poly counts lower. I wanted to capture the main aspects of the toy since I did not have the actual toy to reference from. I have included the PBR materials just in case it does not automatically plug them in. I have seperated the rigged from the non-rigged blender file just in-case you do not need it. The rigged file had some complications with auto-plugging in the materials so those need to be connected. I have tested this model in Unreal Engine 4 and can confirm that the model loads in and works. The glass material does not auto plug in for Unreal from the fbx and will need to be connected.
