Hi, everyone.
Today, I am start to leaning NGUI and whatch this tutorial"NGUI 3 Tutorial".

In this video tutorial 11:25-, there are "2D UI" and "3D UI" in the top right corner.

But in My Unity, I could not find "2D UI" and "3D UI"..

How do I solve this problem?

I have read previous posts, but I could not find..
Please help me

My Unity version is 4.2.2f1 and My NGUI version is 3.0.2.

Click on the Layers button, then click the Edit Layers... at the bottom. You will be presented with a list of both layers and tags that have a bunch of empty slots. In those empty slots, add your own layer/tag names that you want to use. In this case, create a layer called 2D UI and 3D UI (or different names if you wish).

From that point on, you will always have those new layers/tags available for use both in code and in the Editor and NGUI.
