> Prims in linked sets disappear when you zoom in on them because of the rendermaxnodesize default setting of 4096 is too low. Setting this variable to 8192 correct this behavior in the majority of cases without severely hampering viewer performance.
> This defect is not present at all in v1.22.
> In the video (To be attached or referenced) I change the value of rendervolumeLODFactor from 4 to 3 to 2 to 1 and then step down to 0.7 then step back up to clearly demonstrate the "vanishing prims" effect. The prims are there. They are not being turned transparent. The textures on the vanishing prims do not have an alpha channel. The camera is not within the sculpty sphere boundaries. If you edit the linked prims you can see their outline in the viewer. Something in the code related to the render volume LOD factor seems to be the culprit. Note that only some of a prim type disappears and it is always the same ones in the set. Other sculpts in the same set do not vanish yet are identical in size and use the same sculpt map. More than one sculpt map is involved.
> This does not appear to be a duplicate of VWR-13097, VWR-12987, VWR-13038, or VWR-13471 as Linden Lab claims fix pending and some residents are reporting fixed while this defect remains present. This defect is unrelated to alpha transparency.
