I created a mosaic dataset from ~ 360 rasters of aerial photos in .jp2 format. 7 of them wouldn't come in, so per ESRI support, I created a separate mosaic out of those 7, and added them to the original. RGB format. Cool, looked good. I then ran Build Overviews, and everything went grayscale and now I have the image below.
In the mosaic attribute table, there's about 1000 overview features. I've never worked with mosaics before, but don't the overviews go in a separate folder? More importantly, is there a way to fix this without having to add all the rasters in a whole new mosaic? Thanks.
