Hello, this is pretty much a shot in the dark...

i remember time ago i saw a compound (or was it a ICE compound+render tree combination) which will render out in gradient colors the elevation of the geometry.

for example like this

then i want to assign to each color a different shader. Anyone remember which compound it was? i'm tryin to find it but no success atm.

Thanks

by elevation you mean the point poistion in Y axis?

if so, here is a rough example... I didnt add the colors you talk about, as that is not key to solving the problem. cheers

Thanks for the help Gustavo, i used the Lagoa node which i just tried and worked, looked inside and it does exactly what you did

now off to understand how to assign different materials to those areas from the render tree!



thanks!

What about connecting the scalar output of the weighmap lookup into a mix2color node?

Can you not just do this directly in the render tree? No need for ice trees, apply an xy texture projection and give it a grad from top to bottom. use the grad to drive a mix2colours.

For mixing more than 2 materials you can use the gradient mixer (those little color thingys are texturable)

mattmos is right... I feel silly

well apparently...that was easy
Didnt really think about it!

Thanks everyone, worked perfect!

Learn something every day! I'm thinking loading some DTM/DGM into Softimage and trying this!

Not sure if it still works, but there's the old Lume Landscape shader that did all this as well.
