When attempting to add a scene layer package to ArcGIS Pro, no features display in the scene.
The Scene Layer (SPK) is created by a third-party application that incorrectly mixes two compression methods, gzip and zip (deflate). This behavior is seen with older versions of ContextCapture (prior to Update 4). The SPK does not properly follow the i3s specification, leading to unexpected behavior in ArcGIS Pro.
Note: If using an older version of ContextCapture, update to Update 4 or newer.
