* For all you people out there that don't know, you need to add user- in front of his blood mod (or maybe it's mine), because he forgot to (either that or he didn't know he needed to). *
1. Download any ol' blood mod.
2. Extract the file into a folder.
3. See how it works.
4. Replace your blood pics with the ones there.
6. Change the shader file and human_hard / _lite.tik so it works with your files.
7. Pak it back up.
8. Put it in your main folder.
