I’m a little experienced in Unreal Engine, but I don’t know the Unreal’s graphics programming from a very low level. More in details I would like to know how could use an Unreal’s Global Shader to apply some pre-processing operations on to a static mesh and a skeletal mesh as for example creating different LODs. There are some tutorials the could be helpfull ? Someone has experience about pre-processing operations in Unreal ?

Many thanks
