Hi, i have exported to .x and tried the use nuclear glory with it once before, it didn't work. I suggest use the export heightmap as bitmap (or something like that) way and use it to make a terrain. Or use the example that comes with it to load it as a darkbasic matrix, as for collision use
'matrix number = 1
'player number = 1
if object position y(1) < get ground height(1,object position x(1),object position z(1)) then 'what you want to happen on collision event
for a matrix
'matrix number = 1
'player number = 1
if object position y(1) < get terrain height(1,object position x(1),object position z(1)) then 'what you want to happen on collision event
for terrain.
Note, this is untested code but it should work
Sorry if i didn't help,
Hepy
