Pathfinding Server Bugs
- The collision pipeline has been reorganized.
This may affect avatar collisions/control, vehicle movement, and collision callbacks in LSL scripts.
- The terrain collision shape has been changed from a “heightfield” to a “mesh” to provide more efficient collisions, ray-trace, and navmesh computations
- This may change some collision details
- When changing the terrain its visible appearance will update immediately, but its collision shape will not.
- The server will wait at least 10 seconds since the last change before computing the new shape, and the computation time may take several seconds.
- Where there is a discrepancy between visible and colliding terrain shapes, object and avatar collisions may appear incorrect.
- After the terrain is edited, the physics engine needs to 'rebake' the terrain to reflect the new shape, due to the new physics modeling system.
- New accounting system for legacy prims
- All legacy-style prims have their streaming cost capped at 1.0 (except for sculpts, which will be capped at 2.0).
This provides the benefit of not penalizing prim-based creators for optimizing their content by opting into the new system and will make the streaming cost more reflective of the true network cost of the objects. - Server cost will be adjusted to MIN{ (0.5*num_prims) + (0.25 * num_scripts), num_prims }.
This preserves the current value for unscripted linksets and reduce the cost for linksets containing fewer than 2*num_prims scripts.
It provides the benefit of rewarding creators for reducing the number of scripts in their objects. - More info here
- Some discussion of the new costing starts at message 62 on this page
- Vehicle problems
Fast vehicles can snag on the terrain (which now collides as a mesh shape instead of a heightfield)
SVC-8048 Vehicles being very erratic and jittery

SVC-8117 Vehicles being very erratic and jittery on all sl mesh land
