Gradient + Transparent
Hello. Previously, this did not come across. The gradient shader, add transparency map on the similarity of the standard "Unlit / Transparent". I would be grateful for your help.
Shader "Unlit/LinearGradient"
{
Properties {
_TopColor ("Color1", Color) = (1,1,1,1)
_BottomColor ("Color2", Color) = (1,1,1,1)
}
SubShader
{
Pass
{
CGPROGRAM
#pragma vertex vert
#pragma fragment frag
#include "UnityCG.cginc"
fixed4 _TopColor;
fixed4 _BottomColor;
struct v2f {
float4 position : SV_POSITION;
fixed4 color : COLOR;
};
v2f vert (appdata_full v)
{
v2f o;
o.position = mul (UNITY_MATRIX_MVP, v.vertex);
o.color = lerp(_TopColor,_BottomColor, v.texcoord.y );
return o;
}
fixed4 frag (v2f i) : SV_Target
{
float4 color = i.color;
color.a = 1;
return color;
}
ENDCG
}
}
}
Shader "Unlit/LinearGradient"
{
Properties{
_TopColor("Color1", Color) = (1,1,1,1)
_BottomColor("Color2", Color) = (1,1,1,1)
_MainTex ("Main Texture", 2D) = "white" {}
}
SubShader

Tags { "RenderType" = "Transparent" "Queue" = "Transparent" }

o.color = lerp (_TopColor,_BottomColor, v.texcoord.y);
return o;
}
fixed4 frag(v2f i) : SV_Target

Just change the alpha value for each colour as a multiplication for the texture's alpha.
Thank you for your response, your script is useful but I meant another.
Ah, ok. I'll fix it for you. I thought you meant you wanted the gradient as transparency.
In Unity editor shader is displayed normally. Android and ios assembly disappears transparency map. What could be the problem?
Try checking the material queue. This is a common bug in Unity 5 that I think may be your problem. At the top of the inspector, there should be a little padlock. Next to that is a down arrow. Click this, then "Debug". Select your material and find the material queue. This should be 3000. If it isn't change it. If it is, I'm not entirely sure on the problem.
Thanks, did not know about this option, partly helped solve the problem.
