Can you change ScreenShotCapture Camera?

Question

Hey guys!

I'm making this application where you have a character that will have multiple poses and saved as jpg. For now everything works great!

The thing is, I make multiple screenshots very fast, making the different images fly on the screen while the user waits for the result, which is just ugly.

I would want to add a 2nd camera with a loading screen while the screenshots are taken behind this screen. So, 1st camera would take the screenshot while the 2nd would display a loading scren to the user.

Is that possible? Here what I have right now :

   // Check Date to Scren Capture
         string date = GetDate();
         int sceneCount = 0;
         int pageCount = 1;
         GameObject[] activeScenes = new GameObject[2];
         sceneSelectionElementsParent.SetActive(false);
 
         foreach (int sceneId in scenesToLoad)
         {
             GameObject scene = availableScenesToLoad[sceneId];
             activeScenes[sceneCount] = scene;
             scene.transform.position = sceneLocation[sceneCount].position;
             scene.SetActive(true);
             Debug.Log("Scene " + sceneId + " has been loaded!");
             sceneCount++;
 
             if((sceneCount) == 2)
             {
                 ScreenCapture.CaptureScreenshot("MyCharacter_0" + pageCount + "_" + date + ".jpeg");
                 yield return new WaitForSeconds(0.1f);
                 sceneCount = 0;
                 pageCount++;
                 activeScenes[0].SetActive(false);
                 activeScenes[1].SetActive(false);
             }
         }

I believe CaptureScreenshot can only capture what's on the screen but you can render a camera into a RenderTexture and convert the result into a JPG:

 static void CaptureCamera(Camera camera, string path, int width, int height) {
     var renderTexture = new RenderTexture(width, height, 16);
     var texture2D = new Texture2D(width, height);
 
     var target = camera.targetTexture;
     camera.targetTexture = renderTexture;
     camera.Render();
     camera.targetTexture = target;
 
     var active = RenderTexture.active;
     RenderTexture.active = renderTexture;
     texture2D.ReadPixels(new Rect(0, 0, width, height), 0, 0);
     RenderTexture.active = active;
 
     texture2D.Apply();
     System.IO.File.WriteAllBytes(path, texture2D.EncodeToJPG());
 }

Very interesting! I'll be checking this out tonight when I come back from work, but it seems like a great idea!

Thanks a lot!

Changed a bit of things here and there, but the general idea behind it is exactly what I needed.

Thanks a lot man :D
