+## Texture compression - generating DDS textures
+To create DDS textures: Download NVIDIA's https://developer.nvidia.com/gpu-accelerated-texture-compression to compress the textures. We have prepared a script for you to convert a batch of textures for you to the correct format and settings. You can run the python script in a command line python PNGToDDS.py with a path to a directory to generate an nvtt file. That file can then be executed with nvtt_export --batch "<filepath>.nvtt". That will generate DDS files for all PNG files in that directory that follow our naming conventions (_basecolor.png, _normal.png, _metallic.png, _roughness.png, and _emissive.png) and use the correct settings for each of these types. Make sure you generate DDS textures with mips.
