Size Map is a powerful profiling tool in Unreal Engine. It helps find bloated assets, unexpected hard references and other memory related issues.
Size Map is super easy to use, but has some caveats developers should be aware of. I discuss Size Map, the Audit Tool, the still super powerful "obj list" console command to profile disk size and in-memory cost for assets.
This lesson is part of my Complete Game Optimization Course for Unreal Engine 5! I dug into Size Map, how to use it and especially a focus on its limitations and pitfalls that you must be aware of.
