I have a very large and detailed dense point cloud of 1.2 billion points from 1,500 cameras. My PC hasn't the memory to mesh this so I guess I need to divide it into chunks, mesh and then re-combine. Please can anyone give me advice on the best workflow for this. I've tried 6 chunks and it has meshed each fine but I am then having difficulty re-combining. Advice on the best method for alignment and check boxes for merging chunks would be much appreciated. Clearly with a model this size tasks take a long time so the trial-and-error approach is taking too long.Screenshot attached. Thanks.
