random prim STUFF.

land impact.

TL;DR,

Prims with materials ( bump, shiny, alpha mask ) can skyrocket land impact
set your prim linksets to Convex Hull, then None.

initially, Land Impact = Prim Count. But after playing with the Materials or Physics Shape Type of an object, different calculations will be applied.

in Build Menu, with an Object Selected

find the More Info button > it should be under the Land Impact total

Weights of Selected >

* Download :* Physics :* Server : 0.5 always for a single unscripted prim

the largest of these numbers will determine the Land Impact. Physics weight varies based on parameters & scale.

Physics Weight can be a problem, especially in Link Sets, to lower it go to ;

Physics Shape Type >

Convex Hull or None } this will set all except the Root to None, as the Root cannot be set to None.

Convex Hull does come with its own side-effects.

as an example, if u had a Torus as an Arch, it would no longer be passable with Convex Hull.

in this case, u could place an Invisible Hollowed Cylinder without Materials to act as the "Physics Shape" of that Torus.

also, the Land Impact shown outside of the More Info window is not always accurate.

quirks

Land impact shown in Build Menu can be inaccurate even when the Physics Shape is changed
Attachments need to be Re-Attached to save Edits made. This goes for everything, not just Prims.
Some Parameters are linked to others in not so obvious ways.
ex, skew & revolutions
Sphere Prims are not given adequate support within LSL.
Prims that z-fight will only do so after Re-Rezzing, & stop z-fighting once Editted again
Recently created Link Sets show inaccurate Link Order to the User until Re-Rezzed
Unlinking Larger Link Sets can cause flickering, or prevent the user from editting the newly unlinked objects.
Tiny Prims are likely to be missed when attempting to select them with Shift+Drag
Pasting Materials on medium/large Link Sets can cause intense lag, flickering, and other weirdness.
There was a change to the normals of the hollow faces on Curved shapes around 4/12/2025, affecting previous prim builds.

Type these in Local Chat to use them

"flr" - Go to floor
"gth 500" - Go to height
"rezplat 16" - Rez Platform

Can be changed under Preferences > Chat > CmdLine

I just use this Shader. Can be used with Masks so that UI is actually visible when used.

Next to Physics Shape Type,
there should be an Eye to toggle visibility of the Physics Shape.

save prims to disk.

Right Click Prim / Link Set > Save As >

Backup - Prim format, uses a unique file type (.oxp) that can be re-imported into SL or OpenSim as regular prims.

Collada - Mesh format, the topology will be based on the LOD your viewer is rendering at the time.

full collaborative building.

Before choosing a method, I advise anyone participating to set their Default Permissions to Full Perms.
Top Menu Bar > Build > Options >

Set Default Permissions
Next Owner : C, M, T

now for the two methods.

Group method
-------------------

Set Default Permissions
Next Owner : C, M, T - and enable Share with Group.

I haven't actually used this method for a build before, so there may be some intricacies I've missed.
In my short testing it will default the prims to the land group if available on rez.
Otherwise it uses the group you currently have active.

Friends List method
---------------------------

Open your Contacts/Friends list

for Firestorm there will be a row of checkboxes next to the names of your friends.
the first 3 columns are permissions you can give them, in this order.
