Hi, everyone!  Hope you're all doing well.

I'd like to start building my own terrain shaders from scratch.  After doing manipulations in the content shaders, I have a pretty good idea what I'd doing.  My main questions are:  For elevation-affected shaders, how do you determine the actual ultimate altitude of your terrain?  Is there a direct correspondence with the altitude in the terrain editor?  Or is it based on some coefficient in relation to the scene size?

Thanks!
