Trying to programmatically achieve this using the python API:
Enable Particles | Unreal Engine 4.27 Documentation
I see someone has posted about this issue in the past and I was wondering if there are any plans to add this functionality or if anybody has manually modified the plug-in to support this? Or if anybody has a work-around to programmatically activate/deactivate their emitters.
The core issue is that no channels are exposed in the MovieSceneParticleSection
Keying Sequencer FX System Toggle track via scripting - Pipeline & Plugins / Editor Scripting - Epic Developer Community Forums (unrealengine.com)
Thank you in advance.
