Collision detection on large meshes

Blitz3D Forums/Blitz3D Programming/Collision detection on large meshes

Hi there.

I'm having trouble working out the bet way to create my terrains. I originally thought about having loads of pre-made terrain tiles that can be pieced together to make a larger map. The advantage of this is collision detection only needs to be done against the terrian tile they are on, also level creation is easier. The disadvantage is lack of lightmapping on the pre-made pieces.

Another idea would be to create my map from one large terrain, then I can lightmap the level. I think the only real disadvantage of this is that the collision detection now has to be againsts this large (with probably 1,000's of polys) single terrain mesh!

What are peoples thoughts on this?
How are other people approching this problem?
