I have a chunk that has 529 Cameras, 414742 tie points, and dense cloud of 128,115,016 points than runs out of memory (32 meg) trying to build the mesh. I tried using the Split in Chunks script, without selecting merge back and exported the 9 chunks of mesh into Zbrush and assembled them there.
As it ran it the first time, I noticed the seductive merge back button, and tried it several times. It builds the meshes, depth maps and then only returns a merged chunk with with just 529 aligned cameras.
Bug, user error? (I tried rebuilding dense cloud, auto save and of course build mesh with all the same result)
I will send the log file to support.
