Are LightWeightInstances still supported?

Hi.

I was trying out the lightweight instances plugin since were currently looking into something with that exact functionality.

I tried to make a very simple setup and all i get is crashes or its not working as expected.

I was following this tutorial (YouTube, might be outdated but the only doc for a setup i could find)

Is this system still beeing worked on or still supported? Seems like its not working at all anymore in 5.7.3

Steps to Reproduce

  • Use a thirdperson sample project
  • Add light weight instances plugin
  • Create a manager (the static mesh actor variant) class + Static Mesh Actor class
  • Setup the manager to use this actor + a mesh for the ISM
  • Drag one actor into the scene and try convert it to a lightweight instance (Actor -> Convert to lightweight instance)

--> Most of the time this will crash with the following callstack

  • When trying to replace them manually with the node “Convert actor to lightweight instance”:
    • Rarely (1/10 times) it works as expected but then there are more than just 3 instances in the array if i look into it
    • Most of the time the actors dissappear but no instance is added to the manager

Hi there,

Unfortunately it seems like support for the Light Wright Instances plugin is no longer actively supported. In the latest commit the dev notes that the code is obsolete & should be deleted at some point. I’ve attempted to find out why this plugin was dropped or if there is an planned/implemented replacement. Apparently there was a planned replacement for it but as far as I can tell there has been no formal announcement.

This might be applicable to your situation: you can edit individual instances of an Instanced Static Mesh Component using the methods outline [here](Instanced Static Mesh Component in Unreal Engine | Unreal Engine 5.7 Documentation | Epic Developer Community under Instance Selection.).
