Hey folks,
I'm stuck on a rough one (Using Maya 7), I have an extremely truncated time frame, and I'd like to know if there are specific methods to shortcut building a mountain and plains geometry...

Specifically:
Would it be quicker to create a nurbs plane, change it to fabric w/ gravity and drop it on a few objects to get terrain irregularity?

Or, can USGS or topographical map data (or even google earth) data be imported and applied to the poly or nurbs plane to create the elevation changes? (Mountain shape)

Or, would I be able to maybe paint a grayscale map in PS and then use it to somehow modify my geometry?

Or, finally... can anyone point me at a good tutorial for mountain building, since I've not found a good one yet.


If the USGS data would work, does anyone have a site that they use to get accurate and easy to use data?

Thanks!
Dave

well I know how you can make hills (not necessarily mountains)...

just make a nurbs plane and use the sculpt geometry tool under surfaces...

use pull and push a few times (sometimes on large strength) and then use the smooth tool and smooth out the rough edges, or if you really don't like all of the hard edges set it on smooth tool and hit flood a couple of times and then push and pull from there...

hmm... lets see what I can make in ten minutes (I'm timing myself I will try to post one in about ten minutes)... (this is more for myself and to show you what can be made really fast)...

ok this is just me showing off (a little) and I know it doesn't look great but come on it took me ten minutes at 330 in the morning to make I'm sure that if you invest even an hour or two you can make it look alot better

ok shoot me i didn't read the rest of your post... anyway here (http://www.celestiamotherlode.net) is a place that has some cool earth (as well as other planet) textures... just the maps not the shaders for the atmosphere. with these maps I made this...

and ofcourse with a little displacement mapping of my own... have fun :thumbsup: hope I helped

No problem, thanks for the help. I'm going to check out your suggested method right now. Trying to make a mountain by draping cloth really was crap... so, time to get this done, so I can move on.

Nice blue marble. Your 10 minute also helped me out a lot... I ended up sculpting out a polygon terrain that I like, so far. Seems a little too smooth for me, but I'm not trying to get any particular type of mountain look other than smoothed from ocean currents... so I guess it works.

Thanks for your help! I'm going to have to work on it, because I'd like to make at some point a model of the mountains on oahu in hawaii. I'm not sure if the sculpt geometry tool is up to that.

Have a good one.
Dave
