Hi,

I import a terrain made in 3ds, but when i try to convert it too terrain i get this error each time (Can't convert - no regular grid).

I tried to create a terrain in med than export it to 3ds, than reimport into med and convert ... i get the same error...

Anyone know what's the problem?

Thx.

The 'no regular grid' error means that the distances between all the
vertices in the X and Y direction are NOT all EXACTLY the same.

If you are re-scaling during the exports or import process, you MUST
scale both X and Y directions by the same amount. And if you are re-scaling
by ANY amount, sometimes small arrors can creep in. Try to avoid any rescaling.

I have noticed that MED trys to 'estimate' a scaling amount on imports,
be sure to set it to exactly 1(one).

Its also possible when you were playing with the heights in 3DS, you 'nudged'
one more more vertices a bit north/south/east/west. Even a mere 0.000001 of a
quant is enough to 'break' a terrain.

If you get the error, just import it (into MED) as a MODEL, then try to fix it.
Models will import with offset vertices. But I dont know of any 'tool' in
MED that can automatically fix the problem.
But Im not a big MED user, so hopefully someone else can help with that part...

Best of luck...

U say ur not a big MED user... so how u import ur terrain into 3dgs... its possible to load it in another way than a terrain.hmp in the engine...?

Simple ... I usually dont use terrains.

Occasionally I use terrains that were manufactured in MED via imported heightmaps.

But mostly I create my own terrains dynamically in-game from heightmaps.
(very advanced stuff, too soon for you I think)
