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?
