Are there grid-wide problems with the prim counters on rental homes?

[JardSorrow]

Here is my issue:  I am allowed 150 prims on my rental.  I was at 148.  I removed quantity 3, 4 prim objects. I rezzed quantity 3, 1 prim objects.  My counter then said I was at 149 prims.  ??????? 0.o  It started happening last month.  I would add a 3 prim object and the counter said I added 6.  BUT when I removed a 2 prim object, it said I only removed 1 prim.  ???????  My friend who rents in another region has had the same problem.

Be sure that you are always watching the Land Impact of objects that you put on your land, not the number of prims in them.  The two figures are often the same, but not always.  The only number that counts -- the one that is shown in World >> About Land >> Objects -- is Land Impact.

It's so horribly complicated - but Rolig is right.

Think of prims as the component parts that make up an object, and land impact as the combined weight of those - which can be a much lower or higher number.

AND changes when you increase, and in some cases, decrease, the size of the object, or its component parts.

AND how you combine those!!! But that's yet another story!

What counts against your land usage is LAND IMPACT. Not number of prims in an object.

It used to be simpler...one prim = 1 land impact.  But with the advent of Mesh objects, LL changed the way LI is calculated.  For those interested in the gory details, here's the algorithm:

For practical purposes, 1 prim usually = 1 LI, but may be much lower if its Physics Type is set to Convex Hull.  Some prims like toruses may have a much higher LI, ESPECIALLY if they are set to Convex Hull.
