we'd like to think of this texture pack as a resource also, if you want to give sm64 your own look feel free to use these as a base for accuracy, just credit them render96 boys & girls
Why do you think that https://github.com/3d-morphable-models/curated-list-of-awesome-3D-Morphable-Model-software-and-data is a good alternative to RENDER96-HD-TEXTURE-PACK
