VRMFirstPerson Settings

[VRMFirstPerson]({{< relref "univrm_firstperson.md" >}}) has the following settings for Renderer:

FirstPersonFlag	Layer	Note
Both	default	Specify parts that are not necessarily separated between first-person view and third-person view.
ThirdPersonOnly	VRMThirdPersonOnly	Specify parts that are not rendered in first-person view.
FirstPersonOnly	VRMFirstPersonOnly	Specify parts that are not rendered in third-person view. The auto-created headless model is used.
Auto	VRMThirdPersonOnly	Automatically create the model in first-person view at runtime and set it to FIRSTPERSON_ONLY_LAYER.

By calling VRMFirstPerson.Setup at runtime, the layer settings described above can be performed. Please call the function explicitly from outside.

Specify the additional render layers for the application

The following layers are defined as constant:

{{< highlight cs >}} public class VRMFirstPerson : MonoBehaviour { public const int FIRSTPERSON_ONLY_LAYER = 9; public const int THIRDPERSON_ONLY_LAYER = 10;

// The following parts are omitted

} {{< / highlight >}}

{{< img src="images/vrm/layer_setting.png" >}}
Set Layer in #9 and #10

Call Setup function at runtime and set LayerMask in Camera

• Call VRMFirstPerson.Setup
• Set LayerMask for first-person camera view and other camera views

{{< highlight cs >}} using System.Collections; using System.Collections.Generic; using UnityEngine; using VRM;

public class SetupExample : MonoBehaviour { [SerializeField] Camera m_firstPersonCamera; // HMD camera

[SerializeField]
LayerMask m_firstPersonMask; // Set a first-person mask (default | VRMFirstPersonOnly, etc.) in HMD camera

[SerializeField]
LayerMask m_otherMask; // Set other masks (default | VRMThirdPersonOnly, etc.) in HMD camera

[SerializeField]
VRMFirstPerson m_firstPerson;

void Reset()
{
    m_firstPerson = GameObject.FindObjectOfType<VRMFirstPerson>();
}

void Start()
{
    foreach (var camera in GameObject.FindObjectsOfType<Camera>())
    {
        camera.cullingMask = (camera == m_firstPersonCamera)
            ? m_firstPersonMask
            : m_otherMask
            ;
    }

    // VRMFirstPerson initialization
    if (m_firstPerson != null)
    {
        m_firstPerson.Setup();
    }
}
