We are using SkeletonAnimation(SkeletonMesh + MeshRenderer).
I've made a custom shader to control some parameters since our characters waddle through water.
Properties{
_Color ("Tint Color", Color) = (1,1,1,1)
_Black ("Dark Color", Color) = (0,0,0,0)
[NoScaleOffset] _MainTex("Main Texture", 2D) = "black" {}
_Cutoff("Shadow alpha cutoff", Range(0,1)) = 0.1
_WaterSurface("Water surface", Float) = 0.1
_MaskHeight("Mask height", Float) = 0.1
_MaskWidth("Mask width", Float) = 0.5
}
SubShader{
Tags { "Queue" = "Transparent" "IgnoreProjector" = "True" "RenderType" = "Transparent" "PreviewType" = "Plane" }
Fog { Mode Off }
Cull Off
ZWrite Off
Blend One OneMinusSrcAlpha
Lighting Off

}Basically some of these parameters vary between characters depending on where they are located.
Is there anyway to change these parameters and have batching work?
