Blender is rendering all file formats with transpancy as boxes without the rest of the image I followed this tutorial to render fire. But, for some reason when I render the images, any image format with transparency just shows a box instead of the image. I can render the image with a background, but not without one. Any idea what would cause this, and how I can fix it? I'm using blender 2.92 by the way.

It should look like this, minus the background.

Edit: Here's the blender file:
just hide your plane in viewport + render.

and you will get this:

i just added an alpha over node with green to your compositing tree so that you can see that the alpha is &quot;there&quot;.
