Returns the asset UObject if it is loaded or loads the asset if it is unloaded then returns the result. Is there a way to do that in Blueprints, or do I need to write a custom c++ function? I need to mass-assign a material to selected Static Mesh Actors in the Content Browser, but the Bulk Property Matrix doesn’t have a Material setting, so I want to BP assets cannot be used as C++ types directly in code, unless they are a subclass of a C++ class. The ESP32 series employs either a Tensilica Xtensa LX6, Xtensa LX7 or a RiscV processor, and both dual-core Get All Assets.
