When I created a multidirectional hillshade in the Raster Function, I can get a beautiful hillshade which is a temporal file. Then I saved my project and closed the computer, after few days, I open the project again, but the hillshade is unaviailable in the Contents (as shown in the Figure below).
I wanna to know how could I solve this question, I want get a stable Multidirectional Hillshade file when I run the Raster Function tool. Or what operations could be used for save the temporal file?
Thank you very much.
