Info on known issue with rezzing objects onto other objects from 2026-06-25.28189172152

Info: issue is the result of rez location being determined by avatar camera location. This is the reason angling the camera down is a workaround. Camera angle doesn't acutally matter, but this works if it puts camera location inside parcel where rezzing is on.

It's actually a bit more convoluted than that. When the viewer sends a
RezObject
message to the simulator, it does not include a single vector specifying where to rez the object. Instead, it sends a ray with a start and end position, with vector parameters named RayStart
and RayEnd
. The simulator casts a ray given on those vectors, and places the rezzed object on the first physical object that the ray hits, The bug is that the sim is doing an early permissions check at the
RayStart
and RayEnd
coordinates, to see if the agent can rez at those 2 positions, and is failing if either position is "no build" for the agent. This check is incorrect because there could be a separate parcel with somewhere _between_ RayStart
and RayEnd
which allows the agent to rez.AlettaMondragon Resident
Maestro Linden In some cases you stand in the middle of a large rez zone on the roadway, it is a prim road, you look down straight or zoom onto the road surface and rez from inventory, and you get the "you don't have permission" error. So there's no other parcel in-between and there is only one object (the road prim) in the way of the ray, then terrain. What might be the reason for the failure in this case?

Can't rez object at { [position] } because the owner of this land does not allow it. Use the land tool to see land ownership.
message? If so, do you have build permission at those coordinates?If you don't have build permission at those coordinates, then it's probably the same issue. You'd have to use a tool like Hippolyzer ( https://github.com/SaladDais/Hippolyzer/ ) to see the RayStart and RayEnd parameters sent in your viewer's
RezObject
message for that rez attempt to know if it's the same thing.AlettaMondragon Resident
Maestro Linden I believe it is that message. It's difficult to catch this because sometimes it happens several times in a row, sometimes only once and rarely. And yes in these cases these are designated rez zones and rez is enabled for everyone. I also make sure I rez within the parcel borders in these cases and it still happens. I'll try to catch it in a way that can give you more useful info.
