RC orthophotos can’t be loaded into MapBox Tilesets. I don’t have this issue with Metashape. I don’t exactly know the reason for this but it appears to be related to geometric rotation.
Hello,
I don’t exactly know what are you trying to do with the ortho as I have no experience with what you have mentioned, but I should mention that our orthoprojection is not a mosaic, but sort of a ortho view detailed render.
This issue looks relate to https://support.capturingreality.com/hc/en-us/community/posts/115003193011-orthophoto-projection-bug
I would not find relations in 2 years old bugs or reports dear user. On the other hand, I do not know MapBox so I cannot provide you with much help here. You could try to ask on our facebook page Capturing Reality Arena, where we have some skilled mapping users who could have already fixed such problem.
