Hey guys,
this is probably very simple to solve but I am new to Terragen and after spending quite a bit of effort (and with that good learning experience) I can still not get my procedural shader merge with my Heightfield loader and need help.
What I am trying to achieve:
I am trying to manually built a crevasse field into a Heightmap derived from a DEM.
1. So I created and modified a procedural shader using this tutorial (Fig 4c)

However I only want this shape to be shown on a very limited area within my DEM heightmap.
Could anybody possibly give me a run down how to do this? Maybe even post a screenshot of a simple node tree showing masking/blending and merging of a basic procedural with a heightmap loader?!?!
VERY MUCH APPRECIATED
thanks guys
I also just purchased v1.10.23 so I am going to try the paintshader now. I am pretty certain there is another way I haven't of yet.
You'll need to do some masking. Ben (aka bigben) has done quite a bit with masking and a search for your topic, while looking for his name, might lead you to find out quite a few cool things to do.
the painted shader is the simplest way of creating a mask.
Just look down at the DEM heightfield, look for the place you want the effect to appear. Paint this area white.
Then just plug the painted shader into a surface layer into th blend shader port. Add your function into the child layer port of the surface layer, and you should be done.
Cheers,

I didn't think of this. Good answer!
CHAMPION!!!!
I knew it was just ONE little tweak I did wrong ... haha
I tried sooo many different things BUT never even thought about the kids (childInput), which was the only thing I didn't try in my approach with the SurfaceShader.
Thanks so much!
