Adding Shaders into 3.0?

So I've been using 2.0.3 for a while now, and when I saw that 3.0 was out and that you could change effects on the fly I was super excited. Unfortunately, it seems that most of the shaders are gone (like the ones from GemFX, CustomFX, etc.) I tried moving the old effects into the shaders folder (and the textures into the textures folder) of a game that had 3.0.1 installed, but when I booted up the game I saw none of the new effects I had added. Am I doing something wrong, or is 3.0 not compatible with those effects?

Shaders in 3.0 are simpler to write. The old complicated layout of older versions does not work with it, sorry. Post your requests in the shader ideas category of this forum abd I'm sure somebody will help porting them.
