Sure! @rosenand, originally I was moving the instances individually using Update Instance Transform, but I suspected it was causing issues with how the velocity buffer was calculated for the instances, and was causing the ghosting (I very well could be wrong about this, there is very little information for this issue). So to remedy this, I spawned a scene component to act as the “mover” for the instances and attached the ISM components to it. This allows you to move the scene component (I used add local offset) instead of the instances directly, which will correctly calculate the velocity buffers for the instances themselves.
Honestly if you ask me, I think it’s kind of dumb that this work around is necessary for faster moving emissives, and I hope a fix will come eventually.
