Emulating cartoon/anime with mixed frame rates? (too tricky?)

Hi all,

I’ve got a cel shader and outliner, as post process materials, with custom depth stencils, and they’re looking great … But I notice what kills the cartoon effect is having these shaders animate at 60fps (anything over 12-24fps).

This Miyazaki tribute displays a mix of typically 12 fps cartoon animation with higher frame rate cgi, and it seems to better capture the humanity of the characters (imo):

So I’m wondering is there a way (preferably Blueprints) to get post process materials rendering at a lower, fixed frame rate – like 12fps? And then would there be a way to sync that with 12fps animation? Say, while everything else renders at 30-60fps?

As with the video, the cartoon elements still track and zoom at the CGI frame rate – and obviously using drawn 2D animation is what they’ve done there.

Thanks so much, I realise this is probably too niche a problem to have a likely solution
