Verry Large Terrain...

As most of you know I am working on a little side project flight simulator.

I want to give it real world terrain, so I found a huge hight map of the world off of NASA's website.

I want to know how to use it in u3d.

Its 21600x10800 in size.

I need to know will u3d load such a large map? And will it make the terrain up close high detail and the stuff far off low detail?

Should I split the map up, and if so how would I use it that way in u3d?

Can I map the thing to a large sphere (earth) and set gravity to always pull things to the center of the sphere? And if so, how would I apply a hight map to the sphere?



Thanks,

SOTHH


PS. Here is the link to it in case any of you wan't to use it: http://veimages.gsfc.nasa.gov/8391/srtm_ramp2.world.21600x10800.jpg

Not without enormous lag or crashing. I suggest splitting the terrain up in at least 4 pieces.

OK, say I split it up. How would I tile the map in u3d?


EDIT:

I just tried doing it with the one map and IT LOOKS AMAZING!!! I Also got a huge texture for it.

How do I apply a detail map over the Earth texture? That way it looks like theres a lot of detail.

I still wan't to know how to split up the maps for speed.

Correct me if im wrong but,
Cant you just cut the map up in smaller images. then make multiple terrains.
(Also very is with one R(torture me if I'm wrong).)

Proof or it never happened.

Not in U3D 2.1. You can, maybe, tile a texture over the terrain that is slightly on. Otherwise, I'd suggest forgetting about the world detail for now.

Possibly a smaller worldmap and a detailmap. p.s. It looked shite when I applied it to an sphere in 3dsmax. (think its my own fault though. I could barely distinguish africa, europe was nowhere to be found.)

Thats not nice, I would send you the files with the GMK but its way to big.

It does look good though but I only get 20 - fps.

If you wan't proof, go to the link, download it and use it.

Thats what I wanted, to tile a detail map over the whole thing. This is one of the first times I have used the terrain stuff in u3d.

Any way, I am not worried about it right now.

I am thinking if I do do it that way I will just cut the USA part out of the image and use it.

LoL, man. I wasn't serious. XD This is the internet! Relax.

Can't you just make a regular terrain - looking - thing?

Also, please remember that most Game Maker enthusiasts won't download anything over 20 megabytes. MS Flightsim is over 2 Gigabytes...

I won't download anything off someone that I don't know what he can accomplish off if there isn't a screenshot provided.

Are you talking to me?

This was just a test thing I did.

I am not using it any more, and I have removed its coding from my project so theres not going to be any screen shots.
