This pack contains several rock formations with high(100k+), medium(15kish), and low(8kish) poly versions. Each version uses built-in Epic LOD. A simple master rock material with a few parameters is utilized, including baked textures, along with tiling versions of color/normal texture maps for optional optimization. Packed ORM includes a metallic edge map for optional use, with separate thickness maps for subsurface. A simple opaque icy/snowy material is also included(250ish instructions) with some parameters.
