Glad I could help! 
If you run into any issues or need clarification feel free to ask. I certainly don’t mind helping. There are definitely some tricks to keep performance up and get the most optimized scene. With UE4’s profiling it can definitely help see where the bottlenecks are happening. There are a few other ways to optimize with dynamic lighting and such to get good results.
Keep at it, and let me know if I can help further.
