I am trying to hillshade a DTM.ers file. From what I can find - Surface - Transform, then Hillshade is perhaps the path I need to take, , but I don't see a Hillshade option under Surface Transform (see image) . The Chat GPT help I was using talked about selecting Hillshade (ChatGPT may also be off track here). Perhaps I need to install something else here. I am using V8 and also have Surface Tools. Any assistance appreciated.

Many thanks and kind regards
