Caveats

  • The prim description is limited to 127 bytes; any string longer then that will be truncated. This truncation does not always happen when the attribute is set or read.
  • The pipe character '|' and the newline character '\n' are not legal in a prim's description. They will be replaced with '?'.[2]
  • Note that when people have "Hover Tips on All Objects" selected in the viewer's "View" menu, they'll see the object description pop-up for any object under their mouse pointer. For that reason, it is good practice to only set human-friendly information in the description, e.g. keys and such.
  • When an attached object is detached, changes made by script to the name and description (of the root prim) of the attachment will be lost. While the object is attached the name and description can be changed but it will not be reflected in inventory. This caveat does not apply to child prims.
  • If texture is missing from the prim's inventory and it is not a UUID or it is not a texture then an error is shouted on DEBUG_CHANNEL.
  • If texture is a UUID then there are no new asset permissions consequences for the object.
    • The resulting object develops no new usage restrictions that might have occurred if the asset had been placed in the prims inventory.
  • repeats is not only used to set the number of repeats but the sign of the individual components is also used to set the "Flip" attribute.
  • In the default texture mapping mode the texture repeats units are in texture repeats per face. In the planar texture mapping mode the texture repeats units are in texture repeats per half meter. This is in contrast to the in-world editing tool, in which the planar texture scaling units are repeats per meter.
  • If render_material is missing from the prim's inventory and it is not a UUID or it is not a material then an error is shouted on DEBUG_CHANNEL.
  • If render_material is a UUID then there are no new asset permissions consequences for the object.
    • The resulting object develops no new usage restrictions that might have occurred if the asset had been placed in the prims inventory.
  • If render_material is provided as NULL_KEY, the glTF Material is removed from face, reverting back to any underlying Blinn-Phong materials.
  • In the default texture mapping mode the texture repeats units are in texture repeats per face. In the planar texture mapping mode the texture repeats units are in texture repeats per half meter. This is in contrast to the in-world editing tool, in which the planar texture scaling units are repeats per meter.
  • Do not rely on Floating Text as a storage medium; it is neither secure nor finalized.
    • Floating text has been altered in past server updates, breaking existing content; future changes may occur.
    • Even "invisible"[3] floating text is transmitted to the client.
      • It can be viewed by anyone with a client that is capable of rendering text that is supposed to be invisible.
      • The network packets that contain the text can be sniffed and the text read.
  • top_size and client values are different, the ranges do not line up, conversion is required. This simple equation can be used: answer = 1.0 - value. See top_size Explained for more information.
  • PRIM_OMEGA on nonphysical objects, and child prims of physical objects, is only a client side effect; the object or prim will collide as non-moving geometry.
  • PRIM_OMEGA cannot be used on avatars sitting on the object. It will emit the error message "PRIM_OMEGA disallowed on agent".
  • If PRIM_OMEGA does not appear to be working, make sure that that Develop > Network > Velocity Interpolate Objects is enabled on the viewer.
  • In the parameters returned by llGetPrimitiveParams([PRIM_OMEGA]), the vector is normalized, and the spinrate is multiplied by the magnitude of the original vector.
  • If texture is missing from the prim's inventory and it is not a UUID or it is not a texture then an error is shouted on DEBUG_CHANNEL.
  • If texture is a UUID then there are no new asset permissions consequences for the object.
    • The resulting object develops no new usage restrictions that might have occurred if the asset had been placed in the prims inventory.
  • repeats is not only used to set the number of repeats but the sign of the individual components is also used to set the "Flip" attribute.
  • offsets and rotation_in_radians are limited to positive values only, unlike PRIM_TEXTURE and GLTF Overrides. To convert a negative offset to positive, add 1, and to convert a negative rotation to positive, add TWO_PI.
  • To clear the normal map parameters from the face (and possibly remove the material), set texture to NULL_KEY (the other parameters must be supplied in this case but will be ignored).
  • Note that whenever any face in a linkset contains a material (i.e. has a non-default PRIM_NORMAL, PRIM_SPECULAR, or PRIM_ALPHA_MODE), the linkset will use the new accounting system.
  • In the default texture mapping mode the texture repeats units are in texture repeats per face. In the planar texture mapping mode the texture repeats units are in texture repeats per half meter. This is in contrast to the in-world editing tool, in which the planar texture scaling units are repeats per meter.
  • If texture is missing from the prim's inventory and it is not a UUID or it is not a texture then an error is shouted on DEBUG_CHANNEL.
  • If texture is a UUID then there are no new asset permissions consequences for the object.
    • The resulting object develops no new usage restrictions that might have occurred if the asset had been placed in the prims inventory.
  • repeats is not only used to set the number of repeats but the sign of the individual components is also used to set the "Flip" attribute.
  • offsets and rotation_in_radians are limited to positive values only, unlike PRIM_TEXTURE and GLTF Overrides. To convert a negative offset to positive, add 1, and to convert a negative rotation to positive, add TWO_PI.
  • To clear the specular map parameters from the face (and possibly remove the material), set texture to NULL_KEY (the other parameters must be supplied in this case but will be ignored).
  • Note that whenever any face in a linkset contains a material (i.e. has a non-default PRIM_NORMAL, PRIM_SPECULAR, or PRIM_ALPHA_MODE), the linkset will use the new accounting system.
  • In the default texture mapping mode the texture repeats units are in texture repeats per face. In the planar texture mapping mode the texture repeats units are in texture repeats per half meter. This is in contrast to the in-world editing tool, in which the planar texture scaling units are repeats per meter.
  • If PRIM_LINK_TARGET's link_target describes a seated avatar...
  • If face is ALL_SIDES then the flag works on all sides.
  • If face indicates a face that does not exist the flag returns nothing.
