Working on my new RPG sim, TatooineRP, I built burned-out ruins (pictured below if the link worked), which came to 101 prims. I wanted to save on prims since it is just scenery and doesn't really need physics and will probably never be edited, so I did the following to turn the 101 prims into a single mesh.
Edited the ruins today by TatooineRP SWRP, on Flickr1) Linked all the objects in Firestorm
2) Exported as Collada (dae)
3) Imported that into Blender (which is free)
4) Select all objects (should already be selected from import)
5) Click OBJECT>JOIN (or Ctrl + j)
6) Export as Collada dae
7) Import Mesh into your sim with Firestorm
Now it is a single mesh counting as 1 prim which saves on the build allowance and I am assuming the physics as well. Much lighter than the 101 prims it was.
The Land Impact also appears as 1 as well.
Hopefully, it accomplishes what I think it will and be less of a burden to the region.
The OLD way I built this was to have all 101 objects, link them, make them phantom and place a single transparent box over them to keep players from walking through. This saves on the physics but doesn't help with the prim count.
Hopefully, this is useful to someone
