Probably familiar to any TA or Engineer who deals with their graphics pipeline, RenderDoc is a tool I have found incredibly useful for debugging graphics in Unreal. Formerly a Crytek internal graphics debugging tool, it was released to the public in 2014. The tool is developed by Baldur Karlsson, and it boggles my mind that a tool this gosh-darn useful has been given to the public for free. Kudos to Baldur and to Crytek. Previously I was using NVIDIA Nsight to view and debug runtime atlased textures, and it was quite slow and somewhat unintuitive to sift through the outputs to find what I was after.
