How to install Tom's Terrain Tool for the Unity Game Engine?

I just bough开发者_如何转开发t and downloaded Tom's Terrain Tool but I can't find instructions for how to install it. I've looked in the downloaded file - it's a compiled file. I've looked on his website and only find instructions for what to do after it's installed. I've googled around for instructions and can't find them anywhere. In fact, the only file I got with the download is a gzip that extracts into TTT.file. Is that the only thing that was supposed to come with the tool? Why isn't there a readme file with it? Can anyone help me out here? Thanks.

From the installation instructions here:

• Created a new terrain 1) Imported a heightmap

  2) Calculated the light map

  3) Imported all the splatmaps, treemaps, etc. you wish to use into Unity as RGB 24bit textures.

  4) If using Unity 2.6, all the textures/maps you intend to use must be set to "readable" in the import settings.

  5) If using Unity 3, all the textures/maps must have their Texture Type set to "Advanced" and then checked the "Read/Write enabled" option.

Once you're installed the Terrain Tools, you will find them in Terrain => Tom's Terrain Tools in the Unity editor.

RoyS describes this process in his post here:

Here's the steps I use to get my terrain into Unity.

1 - Generate your L3DT map via the Wizard if you're unfamiliar with it. Then... File-->Export map-->(select) Heightfield File format - (pulldown) select "RAW" -type in a File Name -check "resize for export" -1025 size (default) Operations-->Alpha Map-->Alpha Express (png)

The raw is your heightmap and the png is your splatmap. Move those to your Assets folder.

2 - Make sure "Tom's Terrain Tools" is installed per his instructions.

3 - In Unity Terrain-->Create Terrain Add your 4 textures in Unity as normal (you can get some nice terrain textures from http://cgtextures.com ) Terrain-->Import Heightmap RAW --Bit16 --Windows

Now you should see your heightmap in your first colour chosen. If the mountains are too high, then go Terrain-->Set Resolution and change the 600 value. Just change those numbers until you get the desired height of your mountains and valleys.

Now for the rest of the colour of your terrain.

In Unity, select your png texture in the Project folder and in Inspector change it to ARGB 32 bit and hit the Apply button. Now you won't get an error message to change it to 32 bit RBGA as you've just done it. Now to add the splatmap...

Terrain-->Tom's Terrain Tools-->Splatmap

If you're sand is in your mountain area and your grass under the sea, then just change the order of your textures until it's right (ie, the terrain paintbrush textures as if you were painting one from scratch - the same ones you loaded above).
