2.1 DirectX shader cache generation error

[Lax]

Hi,

I read in the Ogre2.1 FAQ about the shader generation, to get rid random hitches during gameplay. I'm using the newest Ogre2.1 version from hq.
So what I did is the following:
I created a function, that creates from all available meshes in the resource system entities. Afterwards I move with the camera to force the shader cache generation. But when I try to move the camera I get the following runtime error:

"RenderingApiException": The shader required more input attributes/semantics than what the VertexArrayObject / v1::VertexDeclaration has to offer. You're missing a component in D3D11HLSLProgram::getLayoutPso"

What could cause this message?

Another question:
When loading a scene, a lot of *PixelShader_ps.hlsl and *VertexShader_vs.hlsl files will be generated in the bin folder where also the applications are located. Is it possible to choose a sub-directory to generate those files there?

Regards
Lax
