This pack includes:14 Models of Rocks & Shells (with LOD system); 1024 x 1024 textures.
All models were carefully designed to optimize poly-count (LOD0s are highly detailed for closeups, while LOD2s contain roughly 180 triangles, so you can place a bunch of them throughout the scene) with textures captured via smartphone, to give that photo-realistic impression.
Each model uses 1 single material, to boost in-game performance when your beach has many rocks.
