Basically that. Foliage makes the whole pc lag very much. Maybe I’m doing it wrong?
Using lower settings alone will not save on performance necessarily, even if you have a lot of objects in your scene. If you’re using the foliage tool with anything you’ll want to make sure that you’re doing the following to keep performance up.
- Use multiple LODs for your static meshes
- turn off cast shadows for meshes like Grass. (fewer shadow casting meshes can help performance greatly!)
- use Cull Distances with either a Cull Distance Volume or in the instance settings for min and max values.
We have pretty high-end machines here that we work off of and not using the things above will kill performance.
I hope this helps.
For me personally, and I’m on a macbook pro, I turn off nanite on static meshes that are being used as foliage. After letting the new textures render for a while, it then becomes smooth and the frame rates pick back up.
