Photon Dust - SkinnedMeshEmitter Doesn't Emit on Some Meshes

[lxw404]

Describe the bug?

Currently Photon Dust SkinnedMeshEmitters seem to be excluding some skinned meshes where the legacy skinned mesh emitter does not.

To Reproduce

Spawn this reproduction object:
resrec:///G-Bright-Spark/R-FB57449EA47BE4264A1BBC8D93CE8BDDE63CD373171CD899EC856204F940B1FE

Notice that the PhotonDust system does not emit any particles on the skinned mesh.

Expected behavior

The new particle system should have identical behavior to the LegacySkinnedMeshEmitter.

Here is a log.

PhotonDust SkinnedMeshEmitter Bug - 2025.1.10.1386 - 2025-01-13 01_56_24.log

From our testing this seems to happen to meshes with either no blendshapes, or meshes without bones, both of which are valid skinned meshes and both of which work in the previous system.

I can't spawn the reproduction object, is it set to public?

[Nytra]

@Frooxius It is set to public. It's a public folder.

You could try this direct link instead: resrec:///G-Bright-Spark/R-adb01efa-1463-4b72-8519-202b31e45853

I can't spawn either link @lxw404 @Nytra.

The issue seems that clipboard actions are broken in Beta 2025.1.14.6. Reported: here.

[shiftyscales]

Yeah thanks - discovered that issue because of this and a couple others.

[shiftyscales]

Confirmed that the replication object resrec:///G-Bright-Spark/R-adb01efa-1463-4b72-8519-202b31e45853 can be spawned, and produces the issue observed above, @Frooxius.
Left: Original (unconverted) object
Right: Newly converted object as of Beta 2025.1.14.6

It was discovered in #3546 that this issue seems to specifically occur in the case of skinned meshes that do not have any blendshapes- which the provided replication object does not.

@shiftyscales In addition to that case, we also found that it happens for skinned mesh without bones, but do have blendshapes.
