Legacy lightmap shader doesnt give any specular highlight.

I tried creating a quick lightmap in beast.. i saved it out in photoshop and i brought it back in for use with a legacy lightmap bumped spec shader. The idea was to have a normal light in there interact with the scene to get some bump and specular highlights.

Now the problem is no specular highlights exist in the lightmapped version! Check out the screenshots. Whats up with this. This worked in untiy 2. The normal maps work... just all specularity vanishes.

Unity devs... this cant be on purpose... whats up.

 

The built-in shader you're talking about looks like this:

Code (csharp):

1. Shader "Legacy Shaders/Lightmapped/Bumped Specular" {
2.     Properties {
3.         _Color ("Main Color", Color) = (1,1,1,1)
4.         _SpecColor ("Specular Color", Color) = (0.5, 0.5, 0.5, 1)
5.         _Shininess ("Shininess", Range (0.01, 1)) = 0.078125
6.         _MainTex ("Base (RGB) Gloss (A)", 2D) = "white" {}
7.         _BumpMap ("Normalmap", 2D) = "bump" {}
8.         _LightMap ("Lightmap (RGB)", 2D) = "lightmap" { LightmapMode }
9.     }
10.     FallBack "Legacy Shaders/Lightmapped/Bumped Diffuse"
11. }

So, here's a fixed version I've made recently:

Code (csharp):

1. Shader "Legacy Shaders/Lightmapped/Gnoblin/BumpedSpec" {
2. Properties {
3.     _Color ("Main Color", Color) = (1,1,1,1)
4.     _SpecColor ("Specular Color", Color) = (0.5, 0.5, 0.5, 1)
5.     _Shininess ("Shininess", Range (0.03, 1)) = 0.078125
6.     _MainTex ("Base (RGB)", 2D) = "white" {}
7.     _BumpMap ("Normalmap", 2D) = "bump" {}
8.     _LightMap ("Lightmap (RGB)", 2D) = "black" {}
9. }
10.  
11. SubShader {
12.     LOD 200
13.     Tags { "RenderType" = "Opaque" }
14. CGPROGRAM
15. #pragma surface surf BlinnPhong
16. struct Input {
17.   float2 uv_MainTex;
18.   float2 uv_BumpMap;
19.   float2 uv2_LightMap;
20. };
21. sampler2D _MainTex;
22. sampler2D _LightMap;
23. sampler2D _BumpMap;
24. float4 _Color;
25. float _Shininess;
26.  
27. void surf (Input IN, inout SurfaceOutput o)
28. {
29.   half4 tex = tex2D (_MainTex, IN.uv_MainTex);
30.   o.Albedo = tex.rgb * _Color;
31.   half4 lm = tex2D (_LightMap, IN.uv2_LightMap);
32.   o.Emission = lm.rgb*o.Albedo.rgb;
33.   o.Gloss = tex.a;
34.   o.Alpha = lm.a * _Color.a;
35.   o.Specular = _Shininess;
36.   o.Normal = UnpackNormal(tex2D(_BumpMap, IN.uv_BumpMap));
37. }
38. ENDCG
39. }
40. FallBack "Legacy Shaders/Lightmapped/VertexLit"
41. }
42.  

 

Thank you so much! Worked like a charm.

 

Thanks a million!! I was just about to make a post about it

 

Can Anyone give me any alternate option of Legacy Shader.

 

great job, thanks Gnoblin !

 

Good job very helpfull for me

 

Thanks Gnoblin! Very cool!

 

How do I get this to work in Unity?

 

Save the text file with the ending .shader somewhere in your project tree. Then you should be able to select this shader in the shader tab.

 

I copied it into Notepad, saved it out as " ".shader in my project folder. It shows up in the list in the Project area. When I select it it, the Inspector gives me a few errors at the bottom.

I'm using the newest version of Unity 3.5.0f5 (Pro Trial).

 

Got it. Thanks Tiles.

 

Hi,

Can someone verify that the script written by Gnoblin works in Unity3d 3.5 free? I got a really brightly-lit scene with no specularity when I tried. Didn't seem to work? Interested because it would be cool to retain some specularity when deploying a lightmapped scene to the mobile platform. Thanks.
