Hey guys I was looking at mjp's deferred shadow mapping sample (http://mynameismjp.wordpress.com/samples-tutorials-tools/deferred-shadow-maps-sample/) and have been trying to convert this to my c++ dx11 based engine.
The issues I'm having are with the creation of the view and the orthogonal projection matrix for the directional light.
See bottom post...
Having problems converting MJP's shadow mapping sample to DX11
I have a (non-deferred) DX11 cascaded shadow map implementation using XNAMath in a bunch of the samples that I post on my blog. You could download this one and have a look at the code as a reference.

Well I've adopted the code in your QueryProfiling sample but I'm still having problems seeing anything in the shadow map.
Update: Okay so I've managed to get "something" on my texture. I still think there's something wrong with the viewport and the constant variables. Can someone explain what these variables do exactly ? And how I have to set them to get a correct image.

static const float ShadowDist = 1.0f;
static const float Backup = 20.0f; // -20.0f will give me an image
static const float NearClip = 1.0f;
static const float CascadeSplits[4] = { 0.125f, 0.25f, 0.5f, 1.0f };
static const float Bias = 0.005f;

Update: Well now this seems to look a lot better.

What I did was invert the light direction. Not sure why MJP's light direction was already inverted there(?).
Plus these values:
