Putting boundries on a terrain

[Guest]

I am trying to put a sky and boundries to where my fps camera can go.

I have been making terrains in milkshape and this works well, but now I
tried putting a large geoshpere to interset the plane of the terrain.

When I load it it seems to work fine but as I reach the border of the sphere
I can go right through it the I can't get back in.

Any advice

what are you using for collision detection? perhaps it only cares about normals, and therefore lets you thru the back side of the polygons but not the front (and your normals are facing outwards).

This is what I am using for detection. It is strait out of the collision example

camera = smgr->addCameraSceneNodeFPS(0,100.0f,300.0f);
camera->setPosition(core::vector3df(0,100,0));

scene::ISceneNodeAnimator* anim = smgr->createCollisionResponseAnimator(
selector, camera, core::vector3df(30,50,30),
core::vector3df(0,-100,0), 100.0f,
core::vector3df(0,50,0));
camera->addAnimator(anim);
anim->drop();

what triangles are in your 'selector' object?

[Guest]

scene::ITriangleSelector* selector = 0;
if (node)
{
node->setPosition(core::vector3df(0,0,5));
selector = smgr->createOctTreeTriangleSelector(mesh->getMesh(0), node, 128);
node->setTriangleSelector(selector);
node->setMaterialTexture( 0, driver->getTexture("test.bmp") );
selector->drop();
