[osg-users] Texture projection on terrain and gl_TextureMatrix[0...7]

[Ekaterina Fokina]

Thank you very much for your answers!

Sebastian, according to your last answer, does it mean that it is also possible to project a texture on top of an object which has some other textures in it? Which unit for a texture should then I use?

What I want to realize, is to mark on the terrain a specific area.
The terrain was build with VPB and seems it has alredy some properties and textures in it.
The way how I see it I should project a texture on it ( which will mark an area). But in all small examples I didn´t find and didn´t manage to have a texture on another texture ( that it is still possbile to see both of them).


Thank you!

Cheers,
Ekaterina
