Lesson 0

Hopefully the beginning of a productive and helpful undertaking. Wish me luck!

Lesson 1

Took a while to get the shaders to dump. Thankfully reading the forum thread helped me find the answer to simply launch the .exe from the folder. Might be a good idea to mention this as a possible hiccup in the lesson!

Here is the pixel shader that I dumped, which is for the bloom effect around certain lights.
