Hello,
when creating a dense point cloud from the same photos, same GCPs, same camera position data and same settings (ultra high quality, moderate depth filtering) I get slightly different results each time.  Is that to be expected?  I'm trying to work out which parameters (particularly which level of depth filtering), gives the most accurate results, but it's hard to judge this if the results are different each time.
thanks
Paula

Yes it is to be expected. There's a random picking part so you'll get slightly different results each time.
