I’d like to make a Niagara Emitter with a Sprite Renderer and a variable that controls the sprite Sub UV image size, but I’m noticing that the system won’t let me drag and drop parameters onto the inputs of the Sprite Renderer like it does for inputs on other modules.

Is it possible to set Sprite Renderer inputs using user parameters? If not, is there a workaround to doing it programmatically?

I am wondering the same thing! I would like to use a user parameter to control the sub UV image size in Niagara
