Weird decimation

[JMR]

I've recently observed that during decimation metashape divides the whole mesh into regions and it looks it decimates diferently. It gives the impression that it sets triangle count per cluster as target rather than a global volumetric parameter for cutting the iterative reduction process, so it leads to very noticeable diferences in mesh resolution thus exactness between clusters.
I think there's room for improvement here.

Hello JMR,

What were the mesh model generation parameters? Also please specify the source and target values of the mesh faces in this project, so that we could try to reproduce the problem on a similar model.
