My project has over 7 million vertices, 6 million faces and 12 million tris's.

I'm also new to rendering but it's slowing down my project A LOT.

My scene has a lot of leaves and grass and I bet they are the ones that have a lot of the polygons and are the ones who causes the slowness.

My animation is 800 frames long, and each frame takes ~2-3 minutes to render...

I looked for solutions in the internet, there were some options like: Decimate Geometry; select all vertices and give them a Limited Dissolve option; and for triangle reduction I should do Ctrl+T.

Problem is, there are way too many objects to click and apply these settings manually, is there any way around this? Or maybe there is an add-on that does it all even better?

    $\begingroup$ There is an addon called "Copy attributes menu". It has an option (on pressing Ctrl+C) "Copy selected modifiers". It does exactly what you want. $\endgroup$ – Mechanic May 17 '20 at 18:18

    $\begingroup$ And there is indeed this answer (by satishgoda) in the thread on link in the header. =) $\endgroup$ – Mechanic May 17 '20 at 18:24

    $\begingroup$ I assure you that answer still works - I've just tried it. If it's not working then maybe the objects you're selecting aren't meshes? $\endgroup$ – Ray Mairlot May 17 '20 at 18:35

    $\begingroup$ @Mechanic LOL thank you a lot, I always think that confirmed solutions on the posts are the ones I should always look at, I rarely even bother looking at other un-verified solutions. Anyway this worked and it's a lot easier than what I have mentioned, thanks! $\endgroup$ – lunaLu May 17 '20 at 18:41

    $\begingroup$ to avoid such great numbers (polycount) look over some tuts how to deal with particle system for creating grass and leaves. Duplicated instances are waaay faster to render and view in the viewport. And the memory is used much better. I mean future projects, of course. for this there is nothing that one can do =) $\endgroup$ – Mechanic May 17 '20 at 20:11
