Largest File Size You Can Upload to Second Life

Summary

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

Handle locations of objects.
Get velocities and other physics information, and does elementary physics to keep runway of what is moving where.

The simulator's job is to:

Run the physics engine.
Detect collisions.
Keep track of where everything is
Transport locations of content to the Viewer forth with updates when certain 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 experience. Some of these will likely change over time, and so if you spot something incorrect/outdated, please take a moment to update it.

Important: The telescopic of this page is focused on Linden Lab's official Viewers, keeping in mind 3rd-political 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 together data without a hard limit, and don't add obscure trivia that doesn't practically affect the general inworld experience.

Avatar

Max. # of attachments - 38 combined HUD or torso attachments.
- They can exist viewed past correct-clicking your avatar and choosing Edit My Outfit.
- With the formal introduction of multiple attachments to a unmarried bespeak in Viewer ii.four, you can attach upwardly to 38 total objects, and they can all be attached to a single betoken.

Max. length of Username - All lower case and a maximum of 63 including the '.'(eg; firstname.lastname)
- Older account user names are a combination of the First and last proper name in lower case separated past a period(.)(eg; lilmix.pixelmaid)
- Modern user names are a single proper noun(no period)(eg; john1234) - Max. length is 31 characters
- The Legacy Names for modern user names always shows Resident equally the last proper name. And then the Max is 40 characters in total for a new avatar's legacy proper name(including the space and last proper name 'Resident')
Min. length of Display_Names - At least 1 script grapheme

Minimum number of members in a group: ii
- A group with only i person for 48 hours will exist disbanded (cancelled). Unless the group owns land.
Maximum number of roles allowed in a group: 10 (including "Owners" and "Anybody", which cannot exist deleted)
Maximum Group Proper noun: 35 single-byte characters.
Maximum Group Title: xx single-byte characters.
Maximum Length of a Grouping Find: 512 single-byte characters.
Maximum Historic period of a Group Notice: xiv days.

Inventory

Maximum number of inventory items that can be sent in a folder: 42
- Folders count as items too. This has more to do with packet size limits than cheeky Douglas Adams references.
Maximum number of inventory items that can be contained in a prim: 10,000
Maximum characters in an inventory item proper noun: 63
Maximum notecard line: None, but scripts can only read the first 1024 bytes (was 255 bytes before server version 2021-x-25.565008).
Maximum notecard size: 65,536 bytes
Number of items in the Library: 3,500 as of 2019-08-10
- Verified by hiding the Library and counting the difference.
Maximum number of inventory items displayed in a unmarried inventory folder: Several thousand.
- This was discussed during [1] "the folder will load up to the limit number of items, and remaining ones won't evidence up in the viewer. you still ain them, they aren't lost, only they will be subconscious until the folder size is reduced."
- There is no specified limit for total avatar inventory, very large folders can be split.
- There was word in the Third Party Developers' UG (four/x/2015) meeting about new inventory and login problems from having large numbers of items in a unmarried folder. AISv3 removed server-side limits on the number of items in a folder. Apartment inventories are bad. No one is certain at what number of items in a binder crusade a login trouble. The fix is to clear the inventory enshroud (non the viewer cache) and log into a deserted, empty region then move inventory items into folders and sub-folders. - The problem appears at dissimilar a number of items depending on your computer and connexion speed. Hopefully being on an empty region will give one enough edge to get logged in and do some corrective piece of work before being dropped. If not, you will need to contact support for help. They will divide large folders into smaller groups so you can log in.

Ban line top for "no entry" or "pay to access" (in other words, "allow public access" is turned off, or "allow grouping access" is turned on, in the packet options) is the parcel's ground elevation plus 50 meters (except, if the region has been set to "Cake Parcel Fly Over" in which case the access controls extend to at least 4096 meters). If a user is explicitly banned past name, the pinnacle is the parcel's ground elevation plus 5000 meters. On current viewers this is visible to the full extent.

Maximum number of agents
- Full region: 100 (Typically gear up to 40 on mainland, 55 on Linden Homes regions, but this does vary. Some meeting areas accept this set to sixty and college.)
  - Recent server performance improvements make regions with 60 agents in them perform quite well.

User Found Temporary Mesh limits:

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

174,752 triangles, beyond which additional triangles will appear every bit holes.
The 64k vertices per material is pre-empted past a limit of 21,844 triangles per textile, which is before long reported as Issues-1001. (4/2014 - Run across discussion page)

The import process will continue making new materials across viii 10 21,844 (=174,752) triangles, but the actress triangles then become dropped past the limitation to 8 materials, causing holes in the resulting object. Over the 21,844 triangle limit, the vertex count will start to climb steeply, even with smooth shading, because the materials get highly interspersed. So the same vertices take to appear in multiple cloth lists. So the moral of the story is to stay below 21,844 triangles per material, for now, if you want to avoid some unexpected furnishings.

Since viewer release three.8.4, processing of meshes in the Collada file that have faces assigned to more than than eight materials has changed. Instead of simply dropping the extra material faces, the uploader at present creates a new object to accommodate them. The result is that the single mesh is divided into multiple objects (prims) in a linkset. Thus the limitation to viii materials is removed as far as input is concerned, but nevertheless applies to each of the resulting linked objects actually uploaded. As a consequence it is now possible to upload a mesh with more than 174,752 triangles, although it will be divided into multiple objects.

Navigation

Meridian counter error above 2147483647 meters

Absolute top limit: 2147483647 = ii³¹ − 1 meters, which causes the altitude counter to curl over. Altitudes well below this cause graphics errors probably due to limited floating point number precision.

Maximum texture size - 1024×1024 pixels
- All 2d Life textures are constrained to powers of 2 (east.thou., 128, 256, 512).
- Some textures inworld have a resolution as loftier as 2048×2048; this is due to a previous limit that was college.
- We strongly recommend you use every bit small textures as possible because larger ones swallow more than memory and accept substantially longer to load.
- Where large textures are being forced by import to only 512×512, lower your ...> Preferences >...> UI Size under 1.0, to increase import size to the max 1024×1024.

Minimum texture size - iv×4 pixels
- This means that there are nine possible image dimensions: iv, eight, 16, 32, 64, 128, 256, 512, and 1024 pixels, either horizontal or vertical.
