So here is comperament of object scattering devices with same settings -
First one in 4032:
And second one in 4041:
You can see that device now create a lot of free space and you have no way to increse density in 10 or 100 times - every time you will receive such low-dense results
That changing of behavior was not mentioned in Update Logs, so i think having no ability to create dence images may be not planned and it is bug or so
