Can I export particle system animations as image sequences without desktop recording software?

I have some particle effects in Unity that I would like to export as sequences of images. Is it possible to do that within Unity, or would I have to do something like create a scene with just the particle system in it, use desktop recording software to record the animation and go from there?

Thanks so much in advance for any advice you can give me.

I don’t know of any way to export, but you can do a screen capture of the individual frames without recording software:

With Pro, you can take it further with RenderTextures.
