For better navigation and finding things, I began to organize the assets in the outliner into seperate folders

Now I move on to the meshes and focus on collisions, meshes that can be merged into one, as well as the possibility of reducing the number of meshes in the level if possible. Like with the lights outside the hall, I immediately looked for assets that are also floating in empty space and other assets that aren't visible in the scene. When discovered, I would remove them after determining if their removal isn't noticeable in the level.

Since there are multiple separated assets from the mod-kit that are used to create the level, I went in and in the densest areas, I would merge those meshes as an asset and replace the separated with the merged. I saved the merged pieces into an asset folder in the folder 3Tianqi location. I would choose how big the merge would be based on it's general impact to the level and are either not within the player space or less likely to be interacted with or edited.

Merge Sizes:

BIG = Takes up a ton of space and isn't likely to see edits. Players could still interact/collide.

EX: Large walls, world floor, scenic background set dressing

MEDIUM = Visually present to the player and interactable/in playable space. Add to visual look of location and will repeatedly placed throughout level.

EX: Platforms

After merging, I would then create new collisions for the meshes since now Unreal is no longer tracking rendering multiple asset collisions.
