From the same creator of “The Missing Stars” hack, this tool imports a Wavefront .obj file as the level mesh of any level in Super Mario 64.
Features:
Replace any of the original levels
Select available Object Banks
Map textures to specific collision types
Set “weather” effects (lava, snow, etc)
Set global terrain types (slide, sand, snow)
Set background graphics
User-friendly interface with save/load settings feature
Textures with alpha are still not properly supported, but will be so in further updates. For best results, use 32×32 textures, other texture sizes might be mapped incorrectly.
