Patch di ghiaia Modello 3D

A patch of gravel to use with instancing for multiple purposes in three basic material variants. Each patch consists of a set of of pebbles in seven individual shapes, each in three different sizes without interpenetration and manually edited to reduce the amount of visible seams for tiling. Each of the seven basic shapes has individual UV coordinates combined in one non-overlapping layout for the containing all seven shapes. The gravel patch comes with three basic materials each with diffuse, specular, glossiness and bump/normal maps in 2048x2048 resolution. Polygon counts have been carefully reduced to make subdivision possible if necessary.
