Kingbdogz said it was incompatible, as the lighting in The Aether is not the same as in the overworld.
Yeah, that's what I meant when I said you should see for yourself
and i dont think that the textures for the shaders have the aether textures
The shaders mod doesn't add any textures, it just chages pretty much everything about the lighting engine,
Oh wait, I'm a Grammar Nazi... what am I saying? lol
He was correcting himself...
The Shaders mod is like Dynamic Lights or Optifine, it doesn' really add anything like blocks, items, etc. to the game. The shaders mod is based mostly on the sun, and in the Aether there is none, so you'll need to get the GLSL Shaders for 1.5.1 and find out for yourself.
