Textures for Ogre::Terrain

[MoonWolf]

Could anyone explain how i should prepare textures for Ogre::Terrain? I've read this: http://www.ogre3d.org/tikiwiki/tiki-ind ... n+Textures, several forum topics and still don't understand the idea. I'm able to prepare *.dds files, but what should be in them? Especially normal_height - what about alpha channel, what colours makes what effect? I'm playing with it for few days and still can't understand.

For now it looks like this. I don't know where those white spots came from. And it looks like it's not illuminated by light.


Here are my (current, as i'm experimenting with them a lot) textures:

road.png (740 Bytes) Viewed 349 times

and

road_normal.png (729 Bytes) Viewed 349 times

Diffuse texture should have colour value in RGB channels and specular value in alpha channel.
Normal-Displacement texture should have vector of normal in RGB channels and displacement value in alpha channel.

OK, thanks!

This page is a good friend:

The link to ShaderMap is broken, so here it is: http://shadermap.com/downloads/
You want the shadermap CL.
I think it's free, but it is kind of impossible to learn that from their site.

Yes, it's free for non-commercial use, although if you are commercial then I guess 40 bucks is a very good price for the full package.

As i stated before, i've read this page but couldn't figure out how compose these textures.

But now i'm not sure if this is worth trying as Ogre 2.1 approaches and Ogre::Terrain doesn't have particularly "good press" anyway (;)

[jacmoe]

Me neither. But that's why I recommend that shader command line tool.
It's braindeadly simple: just give it some textures and it will produce 4 of each.
Those 4 needs to be combined, and you can do that in code.
