XM Textures (Specular Maps) - Ezekial711/MonsterHunterWorldModding GitHub Wiki

The XM texture is used for mapping several effects, with each one correlating to a channel.

Red Channel: Controls the mapping of the "FilmThickness," "FilmBlend," and "FilmIOR" parameters in the mrl3, with higher values being more affected.

• Raising the "FilmThickness" applies an rainbow-like gleam to the model

• Raising the "FilmIOR" discolors the model

• Raising the "FilmBlend" increases the intensity of the "FilmThickness" and "FilmIOR"

Green Channel: Controls the mapping of panorama effects (enabled with the "PanoramaTile" parameter in the mrl3).

Blue Channel: Controls the mapping and wave direction of Wave Emission (Enabled with the "UseWaveEmit" parameter and controlled with the "AnimEmitWave" parameter). Waves will flow from higher values (the areas that are most blue) to lower values (the areas that are least blue), with "AnimEmitWave" controlling the speed of the waves.
