The creation and use of global color maps for multi-tiled terrains. I'm mainly concerned with a few key things: If I end up getting it, I'm sure they will be useful. I'm probably not really interested in World Composer (as I have Terrain Composer and currently don't feel the need to create real world terrains), but thank you for the detailed responses about it. I think you might have mistaken all my references to World Machine as World Composer. Thanks for the lengthy responses lazygunn. I think there are quite a few decent video tutorials on the terrain composer website now for things like this Other programs typically used for this would be what you may have your final terrain detailed in, such as World Machine or Mudbox, which have their own methods for generating normal maps.ģ) If you have imported RTP into your project, it will automatically be used as your terrain shader when using World Composer, i'm assuming this is the case when you create any terrain with terrain composer, but you have to go to RTP lodmanager in your heirarchy and enable Unity4 terrain shader in its options This method is fine for non World Machine terrains too i'd imagine as the normal map would help detail lost through distance and increasing the terrain's pixel error too. With 'act' selected on this layer, select 'Export' at the top and you can select it until you it says 'Export' + the file format you'd like at the bottom then if you click that button it will generate a normal map for you that you can use on lower detailed versions of the terrain. If it is created in World Composer, you would grab the highest zoom level terrain for the area you want, import it to Terrain Composer, go to the colour section, look down to the layer selection, add a layer, click the button saying 'layer', select 'file' then 'open' and in the load preset dialogue find normalmap in the 'Output Maps' directory. Where you create your global normalmap can depend on how you created your terrain, because you'll want to make it from the highest detailed version of the terrain you have, as it is there to provide detail for terrain as you lower its resolution. You can set in the RTP lodmanager wether RTP will use the colormap as-is or it will multiply with the detail texture (creating a blend i think?). You can set how far away the colormap blends into your detail textures and ideally your detail textures should correspond to the colour the colormap is at that point. Using World Composer, the colormap would be the satelite imagery downloaded. It can import terrain it creates straight into Terrain ComposerĢ) In RTP colourmaps generally refer to a texture that will cover an entire terrain, this is to not only cover tiling from the smaller textures you are controlling with your splatmaps but to provide nice imagery over distance. It lets you govern how detailed the terrain and its imagery is and lets you make preset areas and organise them, as well as give you tools to overcome problems with satelite images such as unwanted shadows. In case Nathaniel doesn't show up soon I can offer some quick answers that hopefully wouldn't contradict how he would explain Davidġ) World Composer is generally meant for generating terrain from elevation data and satellite imagery (Using Bing's service) downloaded by it.
