public Vector2 textureCoord2 ;

Description

Координата вторичной текстурной развертки в точке столкновения.

This can be used for 3D texture painting or drawing bullet marks. If the collider is not a mesh collider, Vector2.zero will be returned. If the mesh contains no secondary uv set, the uv of the primary uv set will be returned.
