2d animation in 3d scene

In the linked youtube video, if I wanted to emulate the window rain animation on a rendered 3d scene, would it make sense to add this as post process animation using photoshop?

Basic workflow is setup scene in Toolbag and render image, then do the rain animation in photoshop?

I realize there are more dedicated 2d animation softwares but I'd like to see if I could mimic this effect without new software added.

Any general advice is appreciated. The final product is visual novel, but I thought having some added touches like this could add a lot of life and ambience.

Which 3d modeling tool are you using? I would suggest animating in that.

If you make the animation loop, then you only need a short sequence and repeat it forever. Examples: https://duckduckgo.com/?q=rain+cinemagraph&iax=images&ia=images&iaf=type:gif

These are looped videos, but you can apply the same technique to 2d or 3d animation.

Usually I am doing most of the work in Maya. So, after looking into that more, basically you would use bifrost to simulate the rain and then just render it out as a short loop animation looks like?

That seems simple enough, the only complication is that i need to render in toolbag, so i have to export those animation as a mesh. Maybe that isn't a big deal, but I'll have to experiment and see.

What's the final output format? If it's a video file, you could render in passes, rendering some parts in Maya, others in Toolbag, etc. Then composite them together.

yeah that's a good idea. I can use any of the following formats:

• VP9
• VP8
• Theora
• MPEG-4 part 2 (including Xvid and DivX)
• MPEG-2
• MPEG-1

So I think that could be composited in premiere pro if not photoshop.
