== Background ==

Particle sources from attached objects can be annoying or distracting, whether on purpose or accidentally. Similarly, attachments which are light sources can adversely impact the local ambient lighting, particularly in crowded areas where lighted attachments overwhelm the client limit of 6 local light sources.

While it is possible to entirely disable particles and local lights, this is not an optimal solution.

== Details ==

This patch adds two new menu options under the Advanced menu:

* Advanced > Render > Attached Lights

This option (enabled by default), controls whether or not the viewer will render light sources which are attached to an avatar. When enabled, viewer behavior will remain unchanged, and attached lights will render normally. When disabled, attached lights will not be rendered, and will not be taken into consideration when the viewer decides which 6 light sources to render.

* Advanced > Render > Attached Particles

This option (also enabled by default) controls whether or not the viewer will render particle sources which are attached to an avatar. Again, it is enabled by default and when enabled does not affect normal particle rendering. When disabled, attached particle sources will not be rendered.

== Notes ==

These options will affect all avatars visible to the user, including the user's avatar.

The state of these options will persist across login sessions.

Only attached objects are affected when either of these options are disabled; if an attached object is dropped on the ground, or taken into inventory and then rezzed unattached, its light source and particle source will again be rendered. Unattached objects are entirely unaffected by these options.
