Thank you vivekananda\_k, this works perfectly!

For those who don’t know how to add a script to an emitter;

1. Inside your content browser, right-click and choose FX - Niagara Module Script. Name it EasyScale\_MS. Open the file and select all the nodes and hit delete (Output will remain).
2. Visit that link vivekananda\_k provided [Niagara System scale modular script posted by anonymous | blueprintUE | PasteBin For Unreal Engine](https://blueprintue.com/blueprint/shm_t915/) (if the web page says can’t be reached, just refresh) and select all the nodes and copy them. Then you can paste them into your EasyScale\_MS. Connect the Dest pin from the Map Set node into the Output Module then Apply and Save.
3. Open your Niagara system and you can drag your script from the content browser into your emitters. Make sure you place it directly below the Initialize Particle module.
4. Save your Niagara system and enjoy the ability to scale like normal particles.
