Custom shader go to black on android devices.
Hello, im have a shader demo liquid in the bottle. Shader run normaly in editor but have error in android devices. A part of shader become black. I try to read shader file but i did't find where the error. Some one can help me :( This is my picture off error.
And this is my shader :
Shader "Vertex Magic/Liquid" {
Properties {
_MainTex ("Main", 2D) = "white" {}
_MainTint ("Tint", Color) = (1, 1, 1, 1)
_Fill ("Fill Amount", Float) = 0
_WobbleX ("WobbleX", Float) = 0
_WobbleZ ("WobbleZ", Float) = 0
_TopColor ("Top Color", Color) = (1, 1, 1, 1)
_FoamColor ("Foam Line Color", Color) = (1, 1, 1, 1)
_FoamWidth ("Foam Line Width", Float) = 0
_RimColor ("Rim Color", Color) = (1, 1, 1, 1)
_RimPower ("Rim Power", Float) = 0
}

Thanks for reading.
Hello, if anyone have same problem can fix by this: AlphaToMask is not support on devices mobile if not enable antialising x2, so you need turn of it.
