Rending/ Composition - Something a Little Different

Hello,

I might be alone here...but I am wondering if anyone has had any experiencing rendering a scene similar to the picture I have attached?  If so, are there any examples--or tips?

I am having trouble handling the stretching under the height map.  I tried applying a shader with a minimum slope of 90, but it hasn't seemed to do anything.

Thanks in advance!

Terragen doesn't handle straight 90 degree angles well.

You could try using a cube. I think Oshyan once posted a block thing like this, a better version than this.

Transform input shader with world space checked? Masked, of course.

Thank you, Sir.  I'll try to play around with the file you've attached, and will try to search for Oshyan's files to see if I can find the example you're referring to.

I will have to take some time to try to understand what you mean by this. Essentially it's just the height field showing, and the terrain under X altitude is black.


I think the easiest option would be to just edit the part below out after rendered.  I will still attempt to figure it out...even if it means starting over ;)

If you'd use a cube, you should mask the terrain you add by the same size of the cube (by a pretty hard simple shape), minus maybe 1 perecent or a meter or so. Then you'd cover 99.9% of the top and don't get bulgy sides. Try this.

Thank you so much for this example file, overall looks much better after I plugged everything in.  I set the heightfield border blend to 0.01 to get rid of the bubbling that I was initially getting (looked like terrain sitting on a raft) - I believe this is similar to what you suggested.

Here's a quick TG render:




I might just use a cube to cut the height in the future:
