Hi.
I have 8300 photo made by mavic 3e (rtk) and i cannot to create 3d model by dji because of size.
I want to split it into 2 or 3 parts and then create 3d models separately but then gow can i merge these models?

With Agisoft PhotoScan (now called Agisoft Metashape) you can do it. You have to create 2 or 3 chunks (parts), process each of them individually and finally you can merge them
