> Materials created in runtime are not ‘stored’ they are instanciated in memory. If you create the instances inside a blueprint’s construction script, they are probably stored inside the Intermediate folder somewhere, but I didn’t check that.
> When seed is lower, seed values repeat more and instances that have already been created will repeat on meshes more times, reducing the instanciation process overhead and reducing drawcalls when material+mesh are the same.

Dynamic batching can improve that CPU usage a lot, but will cost much more vram to run the game.
