    I am working on a large scene which includes an xpOcean sim, lots of RS Proxies, a large landscape, and Cloners (using multi-instances).

    When I solo a simple parametric objects to work on them and also have all the other objects in layers with viewport visibility turned off my viewport is still slow and jerky.

    Any idea why this is?

    Thanks,
    Greg

      Hi Greg,

      You may want to put elements in your scene into layers. This way, in the layer manager you can turn off procedural elements that may still be calculating even if you solo an object.
      Things that slow down the viewport can be split into 2 categories.

      1. Things C4D needs to draw/render
      2. Things C4D needs to think / calculate (deformers, booleans, generators)

      My guess is you may have turned off things that need to be drawn (visibility), but there are still lots of things C4D is thinking about.

      In the layers panel you can turn the “thinking” bits off.

      Hopefully that helps.

        Hi Greg,

        Yes, as M (area-internal) said.

        But also other parts might affect the performance, like creating shadows (Editor> Options); in many scenes of mine, that is a 20% draw to create.

        Please let me add this: In the
        Attribute Manager> Mode> View Settings> HUD> you can enable the Frames Per Second option.
        This allows you to see what pulls on your resources while switching them on or off. With that knowledge, you hopefully have less work to manage your scene.

        BTW, if I have (for example) Chrome and Google open in the background, my performance is less than optimal.

        Cheers

          Ah, ok, thanks. I had not thought about the other items in the layers. I will investigate!

          Again, Thanks!!

          Greg

            @Dr-Sassi

            Yes, it was the Generator toggle in the layer manager for a cloner of area lights in a far off landscape. about 40K lights. Now I wonder if I can clone RS area lights as multi-instances!

              Thanks a lot, Greg.

              Please think about polygon lights, perhaps merged into one object. Or, if possible, as I haven't seen the project, perhaps just a texture map and a mask to create 40K light sources.

              Cheers

                @Dr-Sassi Thanks, I will consider polygon lights.

                  Hi Greg,

                  Let me know if there is anything else; I'm happy to have a look at it.

                  Enjoy
