In ArcGIS Pro 2.3, I've symbolized a LiDAR point cloud using RGB values and filtered out the points I don't want in my scene layer package. When I open the "Create Scene Layer Package Tool," is doesn't recognize the presence of RGB values as an attribute to cache (see below). If I navigate to the LAS Dataset using the folder icon, the tool sees the RGB values, but I don't get the filtering options I want. I've also tried saving a layer file and loading it into the tool, but it still doesn't include an RGB attribute. Why is this? For now, it seems like python is the only way to force the RGB attribute to be preserved.
