To create a snowy effect, open your shader and make the following changes:
- Replace the properties of the shader with the following ones:
_Color("Main Color", Color) = (1.0,1.0,1.0,1.0)_MainTex("Base (RGB)", 2D) = "white" {}_Bump("Bump", 2D) = "bump" {}_Snow("Level of snow", Range(1, -1)) = 1_SnowColor("Color of snow", Color) = (1.0,1.0,1.0,1.0)_SnowDirection("Direction of snow", Vector) = (0,1,0)_SnowDepth("Depth of snow", Range(0,1)) = 0
- Complete them with their relative variables:
sampler2D _MainTex;sampler2D _Bump;float _Snow;float4 _SnowColor;float4 _Color;float4 _SnowDirection;float _SnowDepth;
- Replace the Input structure with the following one:
struct Input { float2 uv_MainTex; float2 uv_Bump; float3 worldNormal; ...
