I want to apply a post process distortion effect to an area that is larger then the viewport. (distortion reduces the quality of the image so i want to make it bigger, apply the effect then scale it down)

So basically, I want to render everything pre-process to a large framebuffer, sample that, take a rectangle from that, downscale it a bit and pass that to the viewport. Can you show me how I do that?

Hey there,

Just to say, a wonderful series of tutorials, good speed and the best way of structuring one’s project.

What I have experienced as I enabled the blur effect, there suddenly was a problem with the depthbuffer of the terrain.
As I searched really long for a solution I wanted to give it to people here:

In the terrain class after

Engine.GraphicsDevice.RenderState.CullMode = CullMode.CullClockwiseFace;

add

Engine.GraphicsDevice.RenderState.DepthBufferEnable = true;
Engine.GraphicsDevice.RenderState.DepthBufferWriteEnable = true;

This should work

Bye and another time, thank you for the tutorials
