Noob here looking for advice

Greetings all,

Really getting into Blender and Unreal Engine 4.17 as of late. Been successful so far at creating some simple static meshes and really simply worlds. I want to move to creating detailed environemnts and doing game art. Recently loaded the kiteworld (open world demo) and having alot of trouble building lightning or loading meshes into the scene. It takes FOREVER to compile and get started.

I am running:
Intel 4790K 4.0GHZ
Nvidia 980Ti
32gigs RAM

Am I starting my projects wrong perhaps? Any help anyone can provide would be awesome. I really wanna keep pushing forward and learning this tool. Thanks!
