I was trying to create some bubbles. Everything was OK in render preview, but render result becomes completely transparent image. enter image description here

Here you can see render preview. I use HDRi lighting and film transperant. First sample in render process shows a bit of "envelope" of each bulb. enter image description here

Here you can see render at 2-3 samples and it's almost invisible. enter image description here

here is a gif when render runs... enter image description here

Here is my node setup. I can upload my .blend file if you help me how to do this:) Yes, bubbles are visible, but it brings black background and some bugs. enter image description here

And the most interesting thing i found when i tried to save this image with black background without alpha. THIS is the saved rendered image from previous screen!

Here is the comparison between rendered image and render preview at 1 sample. enter image description here And at 2 samples. enter image description here

  • Is this possible to fix camera or rendering setting to get rid of the problem??? I don't really want to change my node setup because i like how it looks.... – Iced Dec 05 '17 at 14:03

    Are bubbles visible if you put channels of the image in UV Image editor to RGB without Alpha? (buttons to the right from the Image selector). – Mr Zak Dec 05 '17 at 14:29
  • I don't see how 'more samples' makes the image disappear if you are using the same amount of samples for the preview and the final render? – Ray Mairlot Dec 05 '17 at 14:32

    Most likely there is nothing wrong with your file. This is an issue with the viewer.

  • Yes bro, this is the save problem. I can see my bubbles if i use alpha over node with black background.... Thank you. – Iced Dec 05 '17 at 15:13
