Hi Daniel , only if you have issues that you can’t fix in 5.3.1
For some reason for me V5.3.0 still do better processing while fusing than 5.3.1 …especially Advanced mode and is much faster when fusing very big objects .
But if you don’t experience issues don’t need to switch …
you can always try out Cloud Compare to see if you can clean some projects better , but I recommend you meshing it back in Revo Scan
I created the tutorial when we had the old 4.2 software without any tools … still usable in some difficult cases .
