I am using the file InstancedModel.fx from the instancing sample and I am trying to use different variations for differnet objects, so I am trying to add the choice of a pixelshader in the techniques:
| int ShaderIndex = 0; |
| |
| PixelShader PSArray[2] = |
| { |
| compile ps_3_0 PSOne(), |
| compile ps_3_0 PSTwo(), |
| }; |
| |
| // Xbox instancing technique. |
| technique VFetchInstancing |
| { |
| pass Pass1 |
{
|
| VertexShader = compile vs_3_0 VFetchInstancingVertexShader(); |
| PixelShader = compile ps_3_0 PSOne();//(PSArray[ShaderIndex]); |
| } |
| } |
You are looking at the version that is working fine. But as soon as I delete "compile..." and use the
(PSArray[ShaderIndex]); which is now commented out, I get the following error:
Building content threw AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

The code should just work because I simply copied it from BasicEffect-sample?! Any help greatly appreciated...
EDIT: Exception occurs only when building for Xbox. On Windows everything works just fine...
