Hi,

I've been looking at this for a while now, and it seems something small is keeping me from getting it working.

I have this terrain, and added a ramp attribute to get some color areas in Y.

What I want is to separate these ramp colors into groups, so I can extract them for further use.
I've been looking at all the attributes, e.g. the partition attribute , but that all doesn't seem to work without the proper filters. And all I can find on this online doesn't work.

What I also want, is to split up the terrain geo based on elevation. E.g. 0-30 dgr = red, 30-90 dgr = blue. I dabbled with some (VOP) attributes here as well, but not getting what I want.

If anyone can send me on the right path with an example, or some tuts online, that would be awesome.

cheers!

Elevation or angle? If you can post a sample hip it'll be easier to help with your exact requirements.

Hi Michael,

That's very useful,the vimeo channel is gold!
Now I have to find 3 hours to go through all that

@mestella: Yes, angle might be the better word. Elevation would be hight, angle would be the steepness of the terrain. But flatter areas would accumulate more rocks, trees etc., steeper areas would have less or none. Or other shaders, mixed by those color mattes.
Oh… and great wiki btw!!

cheers!

that Terrain project vid covers exactly those issues.
