blender add-on directory on macosx

cd /users/yourname/Library/Application\ Support/Blender/2.59/scripts/addons/luxrender/

it's a hidden directory, normally you can find it on Finder

I am trying to make some pure water in a glass bottle and splashed by an ice cube. But  after I tried many ways, I found it's difficult to make it in blender's default render. The light and reflection is too complex for the blender internal render. So I googled some tutorials, they get these stuff done in luxrender. I finally get it, but I am not gonna try that right now, I think I should stick to blender for a little bit. Just to make things simpler and easier. I think I will come back to luxrender or other render engine later.

Here's another one, this should be the 3rd one.I still followed the tutorial of Andrew Price, thanks Andrew!
