Animations are not currently triggerable via UUID. For reasons we won't discuss this is unlikely to change. Despite this, many of us would like to facilitate script triggered animations without the need for an animation file in the contents.
Therefore, I propose a second UUID be granted to .bvh and . anim files which can only be obtained by the creator. Possibly terming it CUID, which would stand for Creators Unique Identifier, or something like that.
Perhaps this can be acheived by only generating / revealing the CUID one time during upload. This could preclude all existing animations, removing the requirement to retroactively allocate them CUIDs.
Alternatively, by adding a right click function to the inventory which would check if the owner matches the creator before revealing the CUID. This might require / facilitate existing animations being allocated CUIDs. Maybe the right click function could trigger CUID generation on first use, which would give creators the choice, and not result in unused CUIDs being generated automatically for existing animations.
