Hi there :)
Thanks to Marek I finally managed to get most of my shaders I've written
to work with the OB SDK.
I've written a couple of shaders in GLSL before I started using the OB
SDK, and now I try to "convert by hand" some of them to HLSL.
My primary target now is a blur-shader.
I tried creating a horizontal blur so far - but it doesnt really look
like vertical blur!?

My next question would be, how I could add another pass (my vertical blur)?
so long
