lower number of polygons for terrain

Hello. I am wondering if there's any possibility to set a lower number of polygons to be generated for terrain?

Just take a smaller heightmap.

I think he is asking a similar very cut down version of my question I posted? How do you set the terrain scene node to be of a lower poly count, i.e. for when it's a lot further in the distance, the problem is it doesn't continue to tesselate to a lower poly count even when it's miles away from the camera, so it's wasted polys on a dynamic geomipmapped terrain, it's kind of ironique. Very limited.

Well, the interpolation results will grow into weird ups and downs instead of something related to the terrain if you go into too low detail. You will probably have to replace the terrain with an approximated mesh or with some pre-rendered image instead. One thing that might be a limitation in the scene node itself is that the original code and enums were calculated for 257x257 vertices max. Since we support larger nodes now, it could be a problem to get to a reasonable limit for really huge terrains.
