Upgraded my terrain with some newer data, much higher resolution now. In an attempt to be frugal with data size, I had too much of the terrain cropped out in the first image. This led to more reworking, cropping larger section out etc.
Now of course the clouds had the perfect seed before non obstructing to the view need some masking [additional camera with distance shader?] but this is off to being a better end result.
If you are viewing, thanks for taking the time. Constructive criticism is welcome.
