As the title said, when I view the rendered result it looks fine and it shows the transparent background : what appears when i press render image

Meanwhile, when i try to export it as a png it has a black background: RGB

I have already tried to change the rgb thing with rgba but it exports as a white circle in a white background : RGBA I do not know what caused this since im fairly new to blender but here are the picture of the nodes in case i did something wrong : nodes In case this is helpful, ill post the blender file here : https://drive.google.com/file/d/11VMxSpttG-cvmPSFXbfLteBW3Jh2ED0k/view?usp=sharing

EDIT: By exporting the image, I meant saving the image in my computer. When I save as RGBA it shows the sphere but no glare effect in what appears to be a white/transparent? background. RGBA While when I save as only RGB it saves as the sphere with the glare effect, but with a black background. RGB

  • $\begingroup$ How are you viewing the saved PNG? Some viewing applications automatically show transparent pixels as black (i.e., essentially ignore the alpha channel) $\endgroup$ Oct 23, 2021 at 14:48

    $\begingroup$ it works fine for me, as NeverConvex says, it may be because of your image editor app? $\endgroup$

  • $\begingroup$ Your Alpha is set to 0 in the Composite node, try setting it to 1, as per default. $\endgroup$

  • $\begingroup$ Try to connect the Render Layers's Alpha with the Composite's Alpha socket. $\endgroup$
