Maxwell Render | Official public forum

I'm setting up a scene with grass, it's a fairly large area. Should I take it that maxwell grass is not using any kind of view frustum culling? .

Just want to check whether or not I need to be very careful how I set up my meshes that contain grass , as in whether or not its worth me doing my own culling on what is out of view.

Thanks

There is a culling %, its at the bottom of the dialogue.

Maxwell won't do frustum culling for anything in general, because stuff that's not in view can still affect the render: cast shadows, show up reflected on objects which are in view, bleed color on things which are in view etc.

Thanks Chaps, that's what I expected to be the case Mihnea thought I'd check just in case grass worked differently.

Maybe you are looking for "level of Detail" parameters, which changes grass density based on the distance to the camera.

Thanks Fernando/Eric , I've sorted my issues it wasn't the level of detail settings . I was setting it up in another package and my ram usage was very different , I just wasn't being efficient with where I placed the grass in maxwell . I had grass way out of view ( camera and reflections) so I've just removed that and all is good.
