Why doesn't Unity Recorder export PNG image sequence?

Hello! I’m a mobile game animator who has been getting into Unity for the purpose of helping engineers integrate more procedural assets. I’ve used recorder on previous projects in which I was able to stage prefabs in the scene and capture PNG sequences.

On this project I’ve created simple sprite animations and particle effects that I would like to export, however I cannot even get this star to show on any of the frames, let alone have the option of alpha which is missing from the format section.

I have tested recording the scene as a movie and it does work.

The star and the camera are both on the default layer and because it is a 2D game it is projected as Orthographic. Would anyone know how I can troubleshoot this further? What can I do to output sprites using image sequencing and are there settings that are preventing from Alpha being an option?

Thank you for any help!

Try this, although I could use some more information about your steup:

Make sure you have the Unity Recorder package installed. If not, go to Window > Package Manager, find the “Unity Recorder” package, and click “Install”.

  1. Create a Recorder by clicking Window > General > Recorder > Recorder Window. This will open the Recorder window.

  2. In the Recorder window, click the “Add New Recording” button and choose “Image Sequence” from the dropdown menu.

  3. Configure the Image Sequence settings:

  • Set the “Format” to “PNG”.
  • Make sure “Transparent Background” is enabled.
  • Configure other settings as needed, such as “Output Directory” and “Frame Rate”.
  1. Verify your camera settings:
  • Make sure your camera is set to the correct layer(s) and that the objects you want to record are in the camera’s view.
  • Check that the camera’s Clear Flags are set to “Solid Color” and the Background color’s alpha is set to 0.
  1. Press the “Start Recording” button in the Recorder window to start recording the image sequence.

Let me know if this helps, if it doesnt there could be something in your projects settings that is causing the issue, if it’s still a problem then I’d like to know what version of unity you are using and which render pipeline etc.
