I know it's not something unity does natively but I've been able to work around with a texture mask, rendering 2 videos, one color and one with the alpha as a mask.
Now I want to implement it in vuforia but on the video playback it seems the guts are running in the plugin and not unity. Is there a simple way to initialize a second video to start/stop with the color video that I can feed into my shader's mask property?
I'm thinking now I should just use 1 video 2x as tall and have the color frame on the top half and mask frame on the bottom. Then on the material I can adjust the uv's to show only the color video half minus the matte area....
As a png sequence, unity takes an empty png and allocates the same size as if it were full of data, a 250 frame (10 sec @ 25 fps) long animation is like 50mb+ on mobile, while the same thing as a 10 sec video is only 1.5mb lol
What do you guys recommend?
In the DefaultTrackableEventHandler.cs script inside OnTrackableStateChanged() instead of calling ontrackingfound and OnTrackingLost I start/stop coroutines.
If the tracker is found it plays an "intro" coroutine and if it's lost it plays "exit" coroutine.
public void OnTrackableStateChanged( TrackableBehaviour.Status previousStatus, TrackableBehaviour.Status newStatus) { if (newStatus == TrackableBehaviour.Status.DETECTED || newStatus == TrackableBehaviour.Status.TRACKED) { //OnTrackingFound(); StopCoroutine("Exit"); StartCoroutine("Intro"); } else { // OnTrackingLost(); StopCoroutine("Intro"); StartCoroutine("Exit"); } }Then in the intro coroutine I start the video, let it play then spawn the other stuff after some delays:
IEnumerator Intro(){ DOORVID.SetActive(true); //my video plane movietex.Play(); //THIS STARTS THE VIDEO FROM BEGINNING yield return new WaitForSeconds(3.7f); Garage.SetActive(true); //turn 3d garage object on Rider.SetActive(true); //turn motorcycle rider on yield return new WaitForSeconds(1.2f); lightfx.SetActive(true); //turn his headlight on, animation plays automatically doorFrameOpen.SetActive(true); //a still frame of the door open DOORVID.SetActive(false); //hide doorvideo plane } IEnumerator Exit(){ DOORVID.SetActive(true); movietex.Play(); doorFrameOpen.SetActive(false); yield return new WaitForSeconds(0.2f); Rider.SetActive(false); Garage.SetActive(false); yield return new WaitForSeconds(0.1f); movietex.Stop(); //STOP THE VIDEO DOORVID.SetActive(false); }
