I have made a heightmap which I need to make some land from. I started off using terrrains, but when you move around the terrain, it keeps changing height and dissappearing/reappearing. I can't use matrices because they're too slow and I've even tried making an object by writing bytes to a memblock and turning it into a mesh.

All I need is either some help on why the terrain doesn't work properly or some other way to do it.

PLEASE!!!

try setting your camera view distance higher that should fix the problem or add in some fog as whats happening when the parts of the terrain go out of view it only looks like its changeing but infact its still the same just the camera playing tricks on you

Thanks, I've got it working but th terrain doesn't come out at the same size - it's not smooth, it's got edges. Is it not supposed to be the same size as the bitmap?

you can scale the terrain like you would an object the heightmap would just be its initial size then you can manipulate it as needed just look under the terrain commands for it just that some times if you have a predefined texture you may also need to scale that so it fits the terrain proper with out it looking stretched

How can you scale the terrain? the only commands I can find are:
make terrain
delete terrain
position terrain
texture terrain

terrain exist()
terrain position x-z()
get terrain height()
get total terrain height()

are there supposed to be more?

The problem is that you are using the incredibly old terrain system that is absolute pants.

What you need to use is the advanced terrain commands that use a heightmap, texture map and detail map. You should find an example how to use them in the help folder where DBPro is installed.

Boo!

I haven't got any advanced terrain help files, but the commands work - I just have no help on them. Do you know why, and is there a way to get them?
