Having an issue with rendering png, movie files or any render with transparency. What I want from the Eevee display viewport render and actually rendering the animation or screen render give me vastly different results. The picture attached will show the color on the left around the model is green (left) and correct blue (right).
display viewport render is OK
If I disable the transparency from the render properties panel under film I get what I'm looking for.
The viewer for the render image is broken and has been broken for a long time.It cannot display luminous pixels that are transparent at the same time.
PNG is a format that can't do that either. It cannot do associated alpha channel correctly.
If you look at the rendered image as color (not color+A)
Or add a black backround and use alpha over to composite you the image over it and you should see if the render is correct.
As for saving the image, save as EXR and everything should be fine.
