i dont install industrial craft 2 because the normal textures looks bad with photo realism 256.
but then i readed your post, i installed it an it looks perfectly, very good work.
but what exactly your mean with "addon" ?
is this a texture pack addon for photo realism or you mean the industrial craft 2 addons with gregtech or something?
i mean, are the industrial craft 2 addons are also with your texture pack?
i am not so good at english, i am italy
