FString::Printf and FString::Format

An example: I have landscape layer infos named “Layer_00”, “Layer_01” and so on in a project. “Layer 000”, “Layer 001”, in another.

Our 5.5 tools just take a Printf format string and an index, and get the correct layer name.

I need a 5.6 compatible method to update all c++ and blueprint tools and keep this customizability.
