When I simplify a mesh from 30M to 1M, there is an overdensity of vertices at regular positions forming a grid.

This does not happen on all my RC projects, but this seems to be more often now.
Any idea of what is going on ?
Thanks !
Hi Jonathan
It’s because the central part is much more dense than the outside areas…
When you SIMPLIFY the model, set the PRESERVE PARTS to FALSE and, say it‘s a 50 mil tris model, SIMPLIFY it to 45 mil and then from the 45 to the desired value ( say 15 mil ) and the density of the triangles will be much more homogenous.
Ah ok !!! I understand now. So vertices are simplified homogeneously inside eachpart but not between parts ? So the boundaries I see (the lines) are boundaries between previously existing parts ?
So we need to first reduce to one part and then simplify !!! Much clearer now ! Thanks.
Ah, that is a good way of dealing with it, thanks Wishgranter!
It is quite interesting that the result of simplifying is exactly the same when done repetedly with the same target number and the same source. That means there is no randomizer in the algorythm like it seems to be the case with alignment. Just for the sake of it I tried it with “Preserve parts” set to true, but again the result is identical.
Is there any chance that this might be fixed at some point?
Because I figure that simplifying several times must have a similar effect on details than, say, saving an image as jpeg several times.
Not to mention the time involved with huge clouds…
Hmm, I just tried the method suggested by wishgranter and even though the mesh seems to change completely, the details do not seem to change to any noticable degree.
So it’s just about time and convenience - in the end the two steps could just be combined without user interference…
