This texture set completely revamps the RealLight textures in the 717 to 4K resolution. 2K Texture set is included for weaker systems or for people who have less VRAM for Prepar3D v5.
Do note there are some negligible color differences between the original 1K textures and these 2K/4K textures.
Tested on Prepar3D v4.5 HF3.
Thanks to OperatorDerp and turbofandude for the help with these textures!
