Sorry for my idiocy but...
I did everything in the tutorial correctly. I added .setLightValue(1.0F) to Stone and Sand in Block.java.
I ran the recompile.bat, it said it completed client recompile, but said it couldn't find the server recompile sources. I ran the startclient.bat and the mod did work to my amazement!
The thing is, there is no client_obfuscation.txt in my conf folder.
I also don't have a final_out\minecraft folder.
What gives?
I do have a ra.class in my reobf/minecraft folder though...
