How Much Land for a Thousand Land Impact Upload Second Life

Summary

The 2nd Life Viewer and simulators have a segmentation of labor, keeping rails of the information that makes Second Life run. The Viewer'south job is to:

• Handle locations of objects.
• Get velocities and other physics data, and does simple physics to proceed rails of what is moving where.

The simulator's job is to:

• Run the physics engine.
• Detect collisions.
• Continue track of where everything is
• Send locations of content to the Viewer along with updates when sure changes occur.

Limits are necessary for all of these components to work together. The list below outlines many of the Second Life numerical limits that affect your inworld feel. Some of these will probable change over time, and then if you lot spot something incorrect/outdated, delight take a moment to update it.

Important: The scope of this folio is focused on Linden Lab's official Viewers, keeping in mind 3rd-party viewers may differ. Cite sources and provide substantiation for limits that aren't provided by Linden Lab. Also, unconfirmed speculation goes on this discussion page. Don't add information without a difficult limit, and don't add obscure trivia that doesn't practically touch on the general inworld experience.

Avatar

• Max. # of attachments - 38 combined HUD or body attachments.
  • They can be viewed by right-clicking your avatar and choosing Edit My Outfit.
  • With the formal introduction of multiple attachments to a unmarried point in Viewer 2.4, you tin can attach up to 38 full objects, and they can all exist attached to a unmarried point.
  • With the introduction of the Bento armature, at that place are 47 attachment points bachelor.
  • With the introduction of Animesh, at that place is a limit of one Animesh zipper, 2 if the resident has premium.
• Max. # of clothing layers - sixty including alpha, tattoo, shoe base, physics, socks, gloves, undershirt, underpants, shirt, pants, jacket, brim
  • On viewers earlier 2nd Life Release 3.7.29.301305, the potential full was still 60, merely limited to 5 items of each blazon.
  • In any example, but one each of shape, skin, optics and hair base of operations may be worn. These 4 basic body parts are in addition to the sixty clothing layers.
• Max Clothing Texture - 1024x1024 px (except 128x128 px for eyes) - Server Side Appearance (and legacy baking on outside grids) will downsize larger textures.
• Max. unassisted fly superlative - Stable hover at current basis pinnacle plus 5020m.
  • You can hands acquire a flight zipper to wing high. Also see flight limit and the Navigation section beneath.
• Common shoe sizes - Traditionally, well-nigh women'due south shoes were designed for a size 0 (goose egg) foot. Men's generally scale upwardly to 14. Newer items (mesh and some sculpted) replace the system feet or conform to the avatar's shape, so adjustments may be necessary.
  • You can check this by going to Edit menu > Appearance and clicking on the Shape > Legs tab.
• Max. length of avatar proper name - 31 for first proper name, 31 for last name, 63 in full (including the space).

• Max. length of Username - All lower instance and a maximum of 63 including the '.'(eg; firstname.lastname)
  • Older account user names are a combination of the First and terminal proper noun in lower case separated past a flow(.)(eg; lilmix.pixelmaid)
  • Modern user names are a single name(no period)(eg; john1234) - Max. length is 31 characters
  • The Legacy Names for modern user names always shows Resident as the last name. So the Max is 40 characters in total for a new avatar's legacy name(including the space and final name 'Resident')
• Min. length of Display_Names - At to the lowest degree one script grapheme
• Max. length of Display Names - 31 characters
  • Display Names can include most Unicode script characters, spaces, and some punctuation.

• Max. avatar speed - 250m/s (with simply attachments to assist)
• Max. teleport speed - 10 teleports per 15 seconds, since SL server 1.27.i

Groups

• Maximum number of groups you lot can vest to: 42 for Basic accounts, seventy for Premium accounts.
  • After downgrading from a Premium account to a Basic business relationship, you lot may not join any new groups until you are a member of fewer than 42 groups.
  • Roles within groups are sort of like sub-groups. In many cases, you lot can use them instead of creating new groups.
• Minimum number of members in a group: 2
  • A group with only 1 person for 48 hours volition exist disbanded (cancelled). Unless the group owns country.
• Maximum number of roles immune in a group: x (including "Owners" and "Everyone", which cannot be deleted)
• Maximum Group Name: 35 unmarried-byte characters.
• Maximum Group Title: xx single-byte characters.
• Maximum Length of a Group Notice: 512 single-byte characters.
• Maximum Age of a Group Observe: fourteen days.

Inventory

• Maximum number of inventory items that can be sent in a folder: 42
  • Folders count every bit items too. This has more to practise with packet size limits than derisive Douglas Adams references.
• Maximum number of inventory items that tin can be contained in a prim: 10,000
• Maximum characters in an inventory item proper noun: 63
• Maximum notecard line: None, but scripts tin can only read the first 1024 bytes (was 255 bytes before server version 2021-10-25.565008).
• Maximum notecard size: 65,536 bytes
• Number of items in the Library: 3,500 as of 2019-08-ten
  • Verified by hiding the Library and counting the difference.
• Maximum number of inventory items displayed in a single inventory folder: Several grand.
  • This was discussed during [1] "the binder volition load up to the limit number of items, and remaining ones won't testify up in the viewer. yous yet own them, they aren't lost, but they will be subconscious until the binder size is reduced."
  • In that location is no specified limit for total avatar inventory, very big folders tin can be split.
  • There was discussion in the 3rd Party Developers' UG (iv/10/2015) meeting about new inventory and login bug from having large numbers of items in a single folder. AISv3 removed server-side limits on the number of items in a binder. Flat inventories are bad. No one is certain at what number of items in a folder cause a login problem. The gear up is to articulate the inventory cache (not the viewer cache) and log into a deserted, empty region so move inventory items into folders and sub-folders. - The trouble appears at dissimilar a number of items depending on your estimator and connection speed. Hopefully being on an empty region will give one enough border to get logged in and do some corrective work before being dropped. If not, you will need to contact back up for help. They will split big folders into smaller groups so you can log in.

Nonetheless, the technical maximum limit is 35 characters, and exceptions to the concierge policy do exist (eastward.g Sandbox - Weapons testing (no damag and X)
• Ban line tiptop for "no entry" or "pay to access" (in other words, "permit public access" is turned off, or "permit group admission" is turned on, in the packet options) is the parcel's basis elevation plus fifty meters (except, if the region has been set to "Block Parcel Fly Over" in which case the access controls extend to at to the lowest degree 4096 meters). If a user is explicitly banned by proper noun, the elevation is the package's footing elevation plus 5000 meters. On current viewers this is visible to the total extent.

• Maximum water height: 100 meters using inworld controls, 255 meters by using a *.raw file upload.
  • Region water superlative is ordinarily 20 meters, and side by side regions should have the aforementioned water tiptop, or else they volition look discontinuous.

User Constitute Temporary Mesh limits:

Because of an apparent bug in the importer stay within these limits.

• 174,752 triangles, across which boosted triangles will appear every bit holes.
• The 64k vertices per fabric is pre-empted by a limit of 21,844 triangles per cloth, which is presently reported every bit Bug-1001. (4/2014 - See discussion page)

The import process volition go along making new materials across 8 10 21,844 (=174,752) triangles, but the extra triangles then go dropped by the limitation to 8 materials, causing holes in the resulting object. Over the 21,844 triangle limit, the vertex count will beginning to climb steeply, even with shine shading, considering the materials become highly interspersed. So the same vertices have to appear in multiple material lists. So the moral of the story is to stay below 21,844 triangles per textile, for at present, if you want to avoid some unexpected furnishings.

Since viewer release 3.viii.4, processing of meshes in the Collada file that have faces assigned to more 8 materials has changed. Instead of simply dropping the extra material faces, the uploader now creates a new object to adapt them. The result is that the unmarried mesh is divided into multiple objects (prims) in a linkset. Thus the limitation to 8 materials is removed as far as input is concerned, simply still applies to each of the resulting linked objects really uploaded. As a consequence it is now possible to upload a mesh with more than 174,752 triangles, although it volition be divided into multiple objects.

Misc.

• Billing and Trading Limits - Includes LindeX currency exchange limits.

Navigation

Pinnacle counter error to a higher place 2147483647 meters

• Absolute height limit: 2147483647 = 2³¹ − one meters, which causes the altitude counter to coil over. Altitudes well beneath this cause graphics errors probably due to limited floating point number precision.
• Highest z-value of an SLurl, that will however teleport you to a positive altitude: 4096
  • This used to be much higher, but is clamped in belatedly model viewers.

Scripting

• Height at which scripts reactivate on a no-script parcel - 50 yard above terrain mesh. Scripted objects that take controls volition go on running when you fly downwards or enter a no-script parcel. (If scripts are disabled in the region debug console, they will not run at any height.)
• Maximum height where scripts can run - none, as long equally the object remains rezzed or attached.
• Maximum script source code size - 65536 unmarried byte characters (that'due south a viewer limit and can be inverse in the config file 'panel_script_ed.xml').
• Maximum script memory size (LSO) - 16384 bytes.
• Maximum script memory size (Mono) - 65536 bytes (the maximum memory available to Mono scripts can be constrained via llSetMemoryLimit).
• Maximum agile listeners per script - 65.
  • Usable channel for each listener - min. -2147483648, max. 2147483647, including the following special channels: PUBLIC_CHANNEL and DEBUG_CHANNEL.

All Viewers

• Maximum texture size - 1024×1024 pixels
  • All Second Life textures are constrained to powers of 2 (e.g., 128, 256, 512).
  • Some textures inworld have a resolution every bit high as 2048×2048; this is due to a previous limit that was higher.
  • We strongly recommend you utilize as small textures as possible because larger ones consume more memory and take essentially longer to load.
  • Where large textures are existence forced by import to only 512×512, lower your ...> Preferences >...> UI Size under i.0, to increment import size to the max 1024×1024.

• Minimum texture size - 4×iv pixels
  • This ways that there are 9 possible image dimensions: four, 8, sixteen, 32, 64, 128, 256, 512, and 1024 pixels, either horizontal or vertical.
