In UE5, there are many different Views one can choose to view stats or data of the world. These can go from visualizing LOD levels in the viewport, to seeing Shader Complexity, to Buffer Visualization or Light Complexity.
Unfortunately, these are not in UEFN, making it really hard to optimize scenes due to not being able to know what is expensive and what isn’t.
If these were added they would greatly help in optimization, and also in different aspects of creating.
