The engine is a wide toolset, so to have a variety of tools you need to have a larger codebase. if you are compiling from source you can start chopping things out, that you don’t intent to use, but do so at your and your projects own risk as there is a good amount of coupling within the engine itself.
unless you are spinning up several forks on your system compiled from source 500GB should be reasonable.
with 2 full binary installed Engine version both together come out to 230GB, with the extra stuff needing to compile the binaries locally 250 to 275 then your projects are as big as you make them.
programs get big.
In all reality I don’t think anyone from Epic would respond to this thread especially as OP is more interested with spamming then actually listening to reason (regardless of the speakers position)
right now you are effectively “asking for the manager” in an open forum, if you are shocked you got push back then maybe you should evaluate things.
