Averaging Multiple Hillshades

[mllobera]

I am using ArcGis Pro 3.4

I have several related questions I hope people can help me with or provide some examples I can revise.

More specific: 

I am trying to use the modelbuilder to average multiple hillshades. At the moment I am having problems with just generating multiple hillshades. Here is the model I have so far,

More generic question:

If I wanted to aggregate multiple rasters that I the model builder is creating in the fly (think adding n number of rasters that are generated with each iteration) what is the recommended way to do this using model builder?

Thanks

what hillshades are you trying to average?  by orientation? by time?

have you seen the multiple directional hillshade function (which can be done with the above by setting the hillshade type to 1)?

I wanted to change both orientation and elevation (but I just started with the former).

Thanks I was aware of the function but still wanted to reproduce the process as a way to focus on the more generic question I posted.

When adding multiple rasters, look into using the Cell  Statistics GP tool  https://pro.arcgis.com/en/pro-app/3.4/tool-reference/image-analyst/cell-statistics.htm. 

You can calculate mean, median, standard deviation, etc.
