Does anyone know if it is possible to use normalmapping for terrains anyway?
Yes, but unless you've got a really highly detailed normal map with only small details, it will look quite horrible. If a normal mapping shader get's tiled, the last thing you would want is one big normal map in my humble opinion.
Isn't it possible to tile a colormap and use a bigger normal map when using external textures and make sure tiling get's done in the shaders itself?? Just a thought,
Cheers
