I’m playing with this shader from the AngryBots project, which animates rain splashing onto the ground by moving an animated texture. My game pauses independently from Time.timeScale as I use the timeScale in the menus, so I instead set animated objects to stop. But this is animating inside of a shader — how can I get this to stop?
Shader "AngryBots/FX/RainSplash" {
Properties {
_MainTex ("Base (RGB)", 2D) = "white" {}
_Intensity ("Intensity", Range (0.5, 4.0)) = 1.5
}
CGINCLUDE
#include "UnityCG.cginc"
sampler2D _MainTex;
uniform half4 _MainTex_ST;
uniform half4 _Color;
uniform half4 _CamUp;
uniform fixed _Intensity;
struct v2f {
half4 pos : SV_POSITION;
half2 uv : TEXCOORD0;
fixed4 color : TEXCOORD1;
};
v2f vert(appdata_full v)
{
v2f o;
half timeVal = frac(_Time.z * 0.5 + v.texcoord1.x) * 2.0;
o.uv.xy = v.texcoord.xy;
// animation of 6 frames:
o.uv.x = o.uv.x / 6 + floor(timeVal * 6) / 6;
o.pos = mul (UNITY_MATRIX_MVP, v.vertex);
o.color = saturate(1.0 - timeVal) * _Intensity;
return o;
}
fixed4 frag( v2f i ) : COLOR
{
fixed4 outColor = tex2D(_MainTex, i.uv) * i.color;
return outColor;
}
ENDCG

On obvious idea would be to pass in a shader param instead of using _Time. Drive the animated shader value with your param and then you can set the param externally from regular code as needed.
