I may be missing something here but I'm trying to apply a SF such that its values are the same as the height grid. How do I do this? I've played around with the RGB Arithmetic functions but just cant quite get the combination I need.

The reason why just a Height Ramp isn't enough for me is that I want a colour scale bar with a histogram of the height elevation.

Any ideas?

Thanks

Ah, I worked it out.

Tools>Projection>Export>Export Co-Ordinates to Scalar Fields

then create a Constant SF with the co-ord value of the bottom of the mesh

then use SF arithmetic function to rationalise the SF to a new value.

Perfect. It looks great.
