I've swapped SCR_ParticleEmitter to ParticleEffectEntity and this seems to work now.

Hello gregfr_3d.
There are multiple issues, I will try to tell you exactly what you should do for each of them.

Hello, first sorry for the delay.

Hello Plate.
We have been looking into this.
Are we correct in thinking that this will need to be available/iméplemented for the following?:

Further information: I found out this is because I am setting the parent of the slot entities themselves. I've fixed it by not doing this anymore and only doing the parent. Perhaps a way to tell a slot manager component to re-parent its spawned children would be useful?

Sorry, please disregard. I believe I am doing something incorrect. My variables do seem to be updating correctly in Live Debug.

One thing to note is that the PreviewAnimationComponent is used inside of SCR_EditorImagePositionEntity. Here they use AnimationControllerComponent::SetIntVariable on line 413, but the PreviewAnimationComponent has an additional function called UpdateFrameStep which has a comment that says: "Perform one frame step to submit graph variable change".

Hello BigBenREDUX.
This has been implemented for one of the future updates.

I made a showcase addon - https://reforger.armaplatform.com/workshop/5E391577C92A1285-RenderTarget-FeedbackTracker.
If you want, I can also send you the addon outside of Reforger's workshop.

Hello Blackburn2015.
Would it be possible to provide more detailed repro for this? Possibly with some Addon on workshop or zip.

I've assigned this ptc to a few different prefabs in the Game Master FX mod and as long as this ptc was setup in them this problem occurred.

The one that works has the ptc defined in the derived prefab, the one that does not work has it defined through inheritance.

What do you mean? There are two prefabs, they reference different ptc, one works, one doesnt.

Can you try specifically giving the not working prefab the path for the particle affect path?
