To extract the HQ textures out of the TFC files you need to have a "tfc extractor"
You can try this on, but this one is for the Paladins game so not for Realm Royale.
But you can give it a go, maybe you'll get lucky.

C or D:\Hi-Rez Studios\HiRezGames\paladins\ChaosGame\CookedPCConsole
For the Realm Royale it should be something similar only the paladins part is different i guess.
But it should be in the CookedPCConsole part...

Then just copy one of those or all of those into the same directory as the tfc exporter. Then drag one of the .tfc files over the paladins_tfc.exe and it will extract.
Know that this tool is made specifically for the "Paladins" game, not sure if it will work for the "Realm Royale" game.
Give it a try.
