I have a shapefile made from a text file:
X Y Z R G B
It defines a vertical plane of points (see image). Usually (in standard symbology) I can use the function "COLOR_RGB("R","G","B")" in the expression string builder to colour these points however, this doesn't work for the 3D view.
I get the error "No feature was found on this layer to evaluate the expression."
Can anyone please suggest why/what I am doing wrong? and maybe help with a workaround?
