也许我有点模棱两可，感谢您，您在评论中提到的内容已经解决，但是现在的问题是。我将向您展示这些图像： 这些是我拥有的2部摄像机：

这是我的主摄像机（ARCore摄像机）显示的内容

这就是（ScreenShot摄像机）显示的内容

Answer 1

您可以使用图层，将每个arcore模型放置在一个图层（例如ARLAYER）中，然后设置相机的剔除蒙版以避免这些模型。

伪代码：

// Set models' layer
foreach (GameObject arcoreModel in arcoreModels)
     arcoreModel.layer = ARLAYER;

// Set camera's culling mask
camera.cullingMask = ~(1 << ARLAYER);
camera.Render();

从其他相机创建屏幕截图相机

var go = new GameObject("screenshotcamera");
// Copy transform
go.transform.position = mainCamera.transform.position.
...
// Copy camera
var screenshotcamera= go.AddComopnent<Camera>();
screenshotcamera.CopyFrom(mainCamera);

使用脚本更新

snapCam = GetComponent<Camera>();

在渲染任何ARCore模型之前进行截图
