I am trying to create a hillshade on my DEM because I need to be able to distinguish features which I can't do in its current state (see picture).
However, when I add the hillshade, it adds a block grey image over the top.
I tried the hillshade again. When I use a stretched render the DEM doesn't appear. I have tried altering the values but it appears to make no difference. So, the same thing still happens, I try adding a separate hillshade layer and it is still a block colour - sometimes grey, sometimes black.
Any ideas as to how I can get the relief on?
