Title: Space Game Starter Kit: Shaders not working
Post by: jfouch on July 19, 2014, 03:47:28 PM
I recently purchased the space game starter kit and everything is working but the shaders. It shows pink for the initial space ship(spawn/being hit effect/space bar effect), planet, and inside the space station. I have all my project -> quality settings set to fantastic. My gpu is a GeForce GTX 660 Ti. Has anyone had this problem with this kit? If so do you know how to fix it?

Can you post a pic? Did you just import the package into a new project, and nothing else? When you select the shaders used by the pink materials, do you see errors? What's the target platform? (DX11?)

See the attached image. The target platform is DX11. I imported the package into the project directly from the assets store. I do not see any error whenever the project is running.

Right -- change the platform to something other than DX11. SGSK is an old package, DX11 didn't exist back then.

If you want them to work on DX11, you will need to do the following modifications to the shaders:

1. DistortionOne.shader -- remove this:
  1. // Upgrade NOTE: excluded shader from DX11 and Xbox360; has structs without semantics (struct v2f members distortion)
  2. #pragma exclude_renderers d3d11 xbox360
2. In DistortionOne.shader, change:
  1.                                 struct v2f
  2.                                 {
  3.                                         float4 position : POSITION;
  4.                                         float2 uv : TEXCOORD0;
  5.                                         float4 screenPos : TEXCOORD1;
  6.                                         float distortion;
  7.                                 };
to:
  1.                                 struct v2f
  2.                                 {
  3.                                         float4 position : POSITION;
  4.                                         float2 uv : TEXCOORD0;
  5.                                         float4 screenPos : TEXCOORD1;
  6.                                         float distortion : TEXCOORD2;
  7.                                 };
3. Still DistortionOne.shader, change this:
  1.                                         // Time-based movement
  2.                                         screenPos = screenPos * float2(4.0, 12.0) + float2(_Time.w * 3.0);
to this:
  1.                                         // Time-based movement
  2.                                         float f = _Time.w * 3.0;
  3.                                         screenPos = screenPos * float2(4.0, 12.0) + float2(f, f);
4. DistortionTwo.shader needs to have the same changes as DistortionOne.

5. Atmosphere.shader, Planet.shader and Refractive.shader need this at the top of the vertex shader:
  1. #if SHADER_API_D3D11
  2.         UNITY_INITIALIZE_OUTPUT(Input, o);
  3. #endif
P.S. You can also just PM or email me your OR# and I'll send you the updated shaders so you don't have to do any of this yourself.
