Hello everyone! I finally finished implementing Deferred Shading as well as Deferred Lighting in my engine. I am now to point where I would like to add some Post Processing Effects and was wondering, what is the most efficient way to set this up and allow multiple effects? I was thinking that I'd have something like this: For each effect, set to render to a single target, call the effects Render method, in the effect's Render method, create a copy of the target before clearing, render the effect using the target I copied (the last effects output texture), set to the back buffer, then render the target.

void NXPPBloom::Render(NXRenderTarget& target)
{
   //Get the last effect output texture before I clear
   NXTexture2D before = target.Texture;

   target.Clear(0, 0, 0, 0);
   
   //Bloom code...
} 

Do you guys think this will work? Is there a more efficient or easier way to do this? Thanks! :)

Hey everyone! I setup a quick post process effect system and got laying effects working! I'm really excited! Haha! It seems to be working fine. I'll post here if I encounter any problems in the future. I'm actually using 5 targets (color, normal, depth, lighting, and final image) in deferred shading, then passing my final image target to my post process manager which then uses one single render target to layer effects! So six targets! (because I couldn't get it working with taking one of my original targets and re-using it lol).
