This plugin replaces all the textures in marathon infinity's lava set with 512x512 versions. I have sought to stay true to the originals and I hope it shows. Version 2 includes major updates to all textures. Bump maps are now supported. Make sure to check that out!
2.0 New release with major texture upgrades and bump maps
2.05 Removal of bright line from texture 018.
