HLSL Rock+Grass Shader

This shader blends two textures (like rock and grass) based on the surface's world-space direction and angle, using dot product math and a Fresnel effect for smoother transitions. I customized it from a tutorial by adding tint controls and fresnel-based blending to simulate natural material buildup like moss or dust. It taught me how to use normals, direction vectors, and procedural blending in ShaderLab.
