composite blend mode not working AGOL; national feature layer masking to boundary, but not within boundary

[ChrisGiamarino]

Hi,

I am trying to mask a FEMA Flood Area Hazard feature layer to the Orange County, CA boundary layer in the New Map Viewer. I am following this tutorial: https://www.esri.com/arcgis-blog/products/arcgis-online/mapping/create-a-clipping-mask-in-arcgis-onl... by John Nelson. 

However, when I group and then blend using Destination Atop, the flood layers only display on the boundary outlines. Anyone know how I can troubleshoot this bug so that the flood layers display within the OC boundary?

Hi @ChrisGiamarino, 

It looks like the Boundary is just an outline in your map. You'll need to style the Orange County boundary layer and apply a fill, that should give you the results you are looking for.
