    I want to change virtual cam's orthographic size by script, but I cannot find how to access this variable. Then I tried to modify main camera's, like Camera.Main.orthographicSize = 1.0f; But it seems not work. Please help, thanks!

    @Gregoryl Hi there, I'm trying to do the same thing, but when I type vcam.m_Lens.OrthographicSize = 8; It says "The name 'vcam' does not exist in the current context". I'm quiet new to Unity, so it might just be me being retarted. Can you help me out?

    "vcam" in this context is just shorthand to refer to current virtual camera in the current script context. Not meant to be taken literally. Can you post the script snippet where you're trying to set the value?

    Code (CSharp):
    1. public void SetFov(int fovIndex)
    2.     {
    3.         vcam.m_Lens.OrthographicSize = fovIndex;
    4.  
    5.     }
    This is in my settings menu script

    You have to get the current Camera, then get its CinemachineBrain component, then query the brain for the current active Virtual Camera, then set its ortho size. There is no hard and sure way to do this, as it depends on how you've set up your game.

    One possible way:
    Code (CSharp):
    1. var camera = Camera.main;
    2. var brain = (camera == null) ? null : camera.GetComponent<CinemachineBrain>();
    3. var vcam = (brain == null) ? null : brain.ActiveVirtualCamera as CinemachineVirtualCamera;
    4. if (vcam != null)
    5.     vcam.blablabla...

    Can you describe your setup a little, and explain more clearly what you are trying to do?

    Lets say you were starting from a blank slate, how would you go about setting up the virtual camera in the most optimal way to make this work? Also, when would the if (vcam != null) statement activate?

    If the slate is blank, you can start by watching these videos:

    I don't know, but this does not work for me. If I am doing this, I keep getting "The type or namespace name 'CinemachineBrain' could not be found" as a reply.

    Do you have 
    using Cinemachine;
    at the top of your script?

    Hey
    I'm trying to change my orthographic size in my virtual camera when my main character collides with an object. I do not really know where to start since I just started coding this year, so any ideas?

    CinemachineVirtualCamera vcam;
    vcam.m_Lens.OrthographicSize = bla

    Hey when I tried that out it gave me these errors
    - "Invalid token '=' in class, record, struct, or interface member declaration [Assembly-CSharp, Assembly-CSharp]",
    - "Invalid token ';' in class, record, struct, or interface member declaration [Assembly-CSharp, Assembly-CSharp]",
    - "Invalid token '}' in class, record, struct, or interface member declaration [Assembly-CSharp]",

    I don't really know why they popped up so here's my code. Also thank you in advance for helping me.

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    using Cinemachine;

    public class ZoomOut : MonoBehaviour
    {
    CinemachineVirtualCamera vcam;
    vcam.m_Lens.Orthographicsize "=" bla ";"

    "}"

    the things inside " " are what had the red underlines

    I think you took my previous email a little too literally. I was assuming you knew a little more about scripting than you do.

    I would strongly advise you to learn a few basics before continuing. It will help a lot. You could start here: https://unity3d.com/learning-c-sharp-in-unity-for-beginners

    Ok so new question, How would I get components of my virtual camera. Like what are some ways I can reference my active virtual camera so I can modify its components.
