Apply post processing to custom vertices

Hello,

I have a problem which I could not figure out the solution.
I’m drawing some textured vertices using graphics->Draw(…) and before calling it I want to apply some effects similar to post processing.
Is there a way to sample the rendertarget just for the incoming vertex & index array?

To clarify:
I draw a texture using custom array and then I want to apply a blur effect on top but without affecting the rest of the scene / draw calls.

U can create custom pass in RenderPath, which outs result to some texture

<command type="scenepass" pass="myPass" output="myTexture" ... />

Also, you need to create material with this pass. Then all objects used this material will be rendererd to separate texture. U can blur this texture and output over scene.

Or u can draw mask of affected objects to some texture and use this mask in your modified blurred shader.

Any tips on achieving this?

u can see github.com/1vanK/Urho3DOutlineSelectionExample

Thanks
