[SOLVED] Highlight / draw ridge edges of terrain

[Lales.Charles]

Hi,

How would you highlight / draw ridge edges of terrain global and object landscape?

For example a screen space shader (or scriptable material) post filter sobel but instead of color based, normal / z based..

 

Would you see smthg simple to do?

Kind regards,
Charles

Hi Charles,

Should be easy to add, just a custom sobel filter + depth filtering.

You can find in attachment very draft attempt to do this:

So the full shader here: sobel.basemat (the main magic in lines 53-54) and you also can somehow use normal as an addition (all commented lines).

Thanks!

Hi Silent,

Simply excellent, thanks!

Stephane helped to make proper use of it and result is quite convincing ;-)

Kind regards,
Charles
