Thanks @OndrejTrhan
Once I have my RAW mesh created in Reality Capture, I export as Model.PLY with Default parameters to clean it in ZBrush. I then import the CleanModel into RC, default parameters. Model is imported with negative Z instead of positive. Same wrong location whatever the model format (PLY, OBJ, FBX)
I have been doing the same routine for years.
I sent you a message with link to models
