Why a "5" rating? Because the author took the textures into a different world, while preserving all that made them great in the first place: There is no major tonal shift here; there is no gratuitous Photoshop/Maya skullduggery. A simple, elegant conversion and upgrade, which, at the same time, brings a new "feeling" into affairs. Thanks for this, friend.
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!
