Description
The M8 file type is primarily associated with Heretic II, a popular third-person action game developed by Raven Software. It is used to store MipMap textures, which are a collection of pre-calculated, optimized sequences of images, each of a lower resolution than the first. These textures are used to increase rendering speed and reduce aliasing artifacts in the game’s 3D environment. M8 files contribute to the detailed and immersive graphics of Heretic II by allowing for smoother transitions and more efficient texture mapping on 3D models.
