I need help. I'm trying to process a PNG photo to make the background transparent. I can't. The photo is rendered as a whole. Instead of a transparent background black. How to create material?

Color > Diffuse Color
Alpha > Opacity
But it looks like Alpha channel from Image Texture node using PNG isn't read at all (looks like it only uses RGB) , so put Separate RGBA in between to use it properly.
e.g.

Something's wrong. An error appears. When adding a channel shader, the alpha is not working. Although in preview all is well

Are you using latest addon version 8.0.35?

I changed the version to 8.0.35 and it worked. Thanks

8.0.37 automatically will connect the alpha output of the image texture to the opacity input unless it is also manually specified.

I tried to use transparent PNG Tree image to operate it,
it still not work. Do you only upadate new version to complete it? no any other operation?
I will try it later.

Present version is 8.0.49 (Archive: https://bitbucket.org/coronablender/render_corona/downloads/?tab=tags) (https://bitbucket.org/coronablender/render_corona/downloads/?tab=tags)Works)
Works as described above.
Anyways, attached is the scene set ;)
