Overview :
MicroSplat is the fastest and most feature-rich terrain shader, with over 500 five-star reviews. From flowing water and lava to simply blending objects with the terrain to anti-tiling features like texture clustering and stochastic sampling, MicroSplat does it all, and faster. It supports up to 32 PRB textures per terrain, unless the 256-texture engine is used.
