2D Sprite can't receive Shadows

hi guys, i have a problem with shadows receiving on sprite
well i have some cute shadow-cast shader:

Code (CSharp):

1. Shader "Sprites/Diffuse/Shadows"
2. {
3.     Properties
4.     {
5.         [PerRendererData] _MainTex("Sprite Texture", 2D) = "white" {}
6.         _Color("Tint", Color) = (1,1,1,1)
7.         [MaterialToggle] PixelSnap("Pixel snap", Float) = 0
8.         _Cutoff("Shadow alpha cutoff", Range(0,1)) = 0.5
9.     }
10.  
11.         SubShader
12.     {
13.         Tags
14.     {
15.         "Queue" = "Transparent"
16.         "IgnoreProjector" = "True"
17.         "RenderType" = "Transparent"
18.         "PreviewType" = "Plane"
19.         "CanUseSpriteAtlas" = "True"
20.     }
21.  
22.         Cull Off
23.         Lighting Off
24.         ZWrite Off
25.         Blend One OneMinusSrcAlpha
26.  
27.         CGPROGRAM
28. #pragma surface surf Lambert vertex:vert nofog keepalpha addshadow
29. #pragma multi_compile _ PIXELSNAP_ON
30.  
31.  
32.     sampler2D _MainTex;
33.     fixed4 _Color;
34.  
35.     struct Input
36.     {
37.         float2 uv_MainTex;
38.         fixed4 color;
39.     };
40.  
41.     void vert(inout appdata_full v, out Input o)
42.     {
43. #if defined(PIXELSNAP_ON)
44.         v.vertex = UnityPixelSnap(v.vertex);
45. #endif
46.  
47.         UNITY_INITIALIZE_OUTPUT(Input, o);
48.         o.color = v.color * _Color;
49.      
50.     }
51.  
52.  
53.     fixed _Cutoff;
54.     void surf(Input IN, inout SurfaceOutput o)
55.     {
56.         fixed4 c = tex2D(_MainTex, IN.uv_MainTex) * IN.color;
57.         o.Albedo = c.rgb;
58.         o.Alpha = c.a;
59.         clip(o.Alpha - _Cutoff);
60.     }
61.  
62.  
63.     ENDCG
64.     }
65.         Fallback "Transparent/Cutout/VertexLit"
66. }

this shader allows my sprites to cast some shadows but they cant be received by them.
how can i add the possibility of receiving shadows in this shader?
spriteRenderer.receiveShadows is ON
spriteRenderer.castShadows is ON too.

P.S. yes, i know that meshRenderer could receive any shadow, but i need to attach this possibility to sprites.
please help!)

 

if you are using desktop then this shader is built into unity? see standard shader drop down for blend modes like Transparent, Fade, Cutout...

 

did anyone received shadow by sprite?

 

Anything with a transparency queue will not receive shadows.

Try "Queue"="AlphaTest" "RenderType"="TransparentCutout" ZWrite On and remove the blend line.

 

i tried now, it does not work :X
here is some explanation about my problem:

bg is mesh with standart shader, it receive shadows easily
if sprite's shadow comes on other sprite, it isnt receiving by it
i turned off bg "receiveShadows":

which part of standart(specular) shader allows it to receive shadows?
must i mix it with my shader or something?

 

You might try adding fullforwardshadows to the #pragma surface line, along with replacing keepalpha with alphatest:_Cutoff

 

nope
which code allows to receive shadows in Unity?

 

OK, i found the solution
if someone needed, you can get it from my github:

Hi @anlev,

Could you please show me how to use your shader in version 5.4 of Unity? You have a sample project? I'm having trouble playing shadows on my sprite object

Please!

 

This shader will create shadows for Sprites, but it will disable partial transparency on the Sprite.
