С lightmap вопрос решен, вот исправленный шейдер:
Shader "Legacy Shaders/Lightmapped/Gnoblin/BumpedSpec" {
Properties {
_Color ("Main Color", Color) = (1,1,1,1)
_SpecColor ("Specular Color", Color) = (0.5, 0.5, 0.5, 1)
_Shininess ("Shininess", Range (0.03, 1)) = 0.078125
_MainTex ("Base (RGB)", 2D) = "white" {}
_BumpMap ("Normalmap", 2D) = "bump" {}
_LightMap ("Lightmap (RGB)", 2D) = "black" {}
}
SubShader {
LOD 200
Tags { "RenderType" = "Opaque" }
