This web content showcases a demo of “megatextures” running on the n64 hardware. A “megatexture” on the n64 is essentially a normal-sized texture by modern standards, but it allows for the creation of prebaked scenes that appear more advanced than what the n64 is typically capable of. To build the rom, several dependencies need to be installed, including the Modern SDK, Blender 3.0 or higher, sfz2n64, mpg123, and sox. The process also involves editing assets/world/test.blend to create scenes with megatextures. Certain specifications, such as material names, texture formats, and sort groups, need to be followed for optimal results.
