Set the opacity of one ordinary Standard/PBR mesh without modifying its material.
Finite values are clamped to [0, 1]. Values below 1 select sorted blending with
depth writes disabled; zero omits colour and geometry draws. Shadows, picking
and mesh visibility are unchanged. Thin instances share their mesh's opacity.
Scene-owned meshes in autoMirror: false tasks follow crossings of 1 only with
enableRenderTaskMeshRefresh, for entries added without a material override,
matching material swaps. Unregistered meshes in an explicit geometry-task
meshes list change pipeline/blend variants only at that task's next renderable
sync, as with material/topology changes; updates below 1 and geometry's zero
skip are immediate. Existing binding values, including 1, update immediately.
