throttles. Setting adaptive_throttle_min_bps will change the
minimum rate that the adapative throttles will drop to in case
of network packet loss. The current rate default rate is 256kbps.
The viewer can throttle rates under that amount, but the dynamic
adaptation will not.
This is implemented with a new collision type (PhantomToOthersAvatar) to potentially allow colliding and non-colliding avatars to be present in the same scene.
So there is no provision yet for giving avatars different collision types.
This commit replaces the temporary change in commit f3eaa6d8 where avatars would never collide when using BulletSim
This is equivalent to the av_av_collisions_off option in ODE.
This is the same as already done for scene_throttle_max_bps
Internally, the token buckets are in bytes and the other help text makes it clear that the number is bytes per second
(though with the wrong assumption that 1 mbit = 1024 * 1024 bits whereas 1 mbit = 1000 kbits = 1000000 bits)
This setting was originally added some time ago to deal with issues where appearance was not received properly by all users.
However, it does not scale well with large numbers of agents.
Disabling to see if the original problem has abated or whether this will have to be tackled in another way.
[Startup] default setting UpdateTempCleaningEveryNFrames becomes UpdateTempCleaningEveryNSeconds.
Default becomes 180s instead of effective 182s (which would also vary with any changes in frame time or extra long frames)
If n > 1 for RootTerseUpdatePeriod only every n terse update is actually sent to observers on same region, unless velocity is effectively zero (to stop av drift).
If n > 1 for ChildTerseUpdatePeriod only every n terse update is sent to observers in other regions, unless velocity is effectively zero.
Defaults are same as before (all packets are sent).
Tradeoff is reduction of UDP traffic vs fidelity of observed av mvmt.
Increasing n > 1 leads to jerky observed mvmt immediateley for root, though not on child, where experimentally have gone to n = 4 before jerkiness is noticeable.
Experimentally, on the Linden Lab grid the avatar can rotate slightly before triggering AvatarUpdates, whereas this is practically impossible in OpenSimulator.
These updates allow other avatars to see rotations, though sensitivity is low since other avatars can only be seen in one of 8 body rotations.
This commit changes sensitivity from 0.01 to 0.1, which better matches LL and reduces UDP traffic which has a beneficial impact on network and CPU load.
This has no impact on rotations in the simulator itself so simulation fidelity is the same as before.
To change this setting back for test/other purposes, edit RootRotationUpdateTolerance in the [InterestManagement] section of OpenSim.ini
Running out of such threads under heavy load causes delayed packet processing which can lead to spurious UDP resends and knock on issues.
We already massively boost the min/max builtin pool worker and IOCP threads (which even with STP are still used for inbound network requests) without obvious adverse effects.
The threads are only instantiated if they are required.
This change does not affect other async_call_method options.
These govern when AgentUpdates are sent to observers on position, rotation and velocity changes to an avatar (including the avatar themselves).
Higher values reduce AgentUpdate traffic but at a certain level will degrade smoothness of avatar and perceived avatar movement.
This, by default, enables terrain patches being sent to each avatar
from the avatar away (rather than the old outside-in pattern), only
sending terrain patches within the avatars view distance (making
view loading quicker), and sending multiple terrain patches per
protocol packet (making terrain loading and editing quicker).
co-op should be more stable as it doesn't abort threads, which can trigger virtual machine instability
This change will be invisible to users as script DLLs are recompiled automatically where necessary, though the change won't take affect until the next simulator restart.
This change has no effect on existing script state.
If you want to continue using abort, set ScriptStopStrategy = abort in the [XEngine] section of OpenSim.ini
This is to allow us to get useful information on messaging without being overwhelmed by the rest of groups debug.
Enabled with [Groups] DebugMessagingEnabled = true in config (default false)
Or "debug groups messaging verbose true|false on the console" (similar to existing groups setting).
Done for both xmlrpc and V2 groups.
config option, LogOverloads, to log when a thread pool overload occurs.
This option defaults to "True" because the logging data is useful for
diagnosing threading issues.
a capsule. Set the default to be the rectangle shape and adjust the
parameters in OpenSimDefaults.ini for the new shape.
The rectangle shape will perform better and avatar height can be
computed more accurately.
One reason support was removed is that the external DLL that implemented Javascript stopped development.
Not sure how well this ever worked in OpenSimulator.
Not removing vb for now as this is directly supported by Mono (via vbnc compiler) though I strongly suspect it is also inoperable.
It originally looked like mesh terrain would perform better for vehicles
but, after much use, heightmap is the clear winner.
Force terrain implementation to heightmap if the physics region is
larger than legacy region size. This solves running out of memory for
very large regions.
udp texture throttle and move it to the task throttle. Since most
viewers are using http textures, the udp texture throttle is holding
onto bw that could be used for more responsive prims updates. See
the documentation for CannibalizeTextureRate in OpenSimDefaults.ini.
Option is disabled by default.
This includes additions to Warp3D:
Optional rendering of mesh and scupltie prims (INI parameter. Off by default)
Texturing of large prims (INI parameter. On by default)
Better garbage collection
The BulletSim plugin is higher performance and has a better implementation of vehicles amongst other things.
Many thanks to Robert Adams for making this possible with the enormous amount of work that he has done on this plugin.
If you want to continue using ODE, set physics = OpenDynamicsEngine in the [Startup] section of OpenSim.ini
This is specified in the MaxOutgoingTransferVersion attribute of [EntityTransfer] in OpenSim.ini, see OpenSimDefaults.ini for more details.
Default remains "SIMULATION/0.2"
