Thanks! I was at the VERY beginning of UE4 4 weeks ago. I recommend the Unreal youtube channel, and start from the beginning. do some searches for “Lightmaps Unreal Engine 4”. Yes everything was built in Maya, merged some meshes, mades some UV’s on channel 1, Lightmaps on channel 2, then exported to Unreal. Materials are modified freebies you can find in the Marketplace.
