I'm trying to create a simple animation. I have have a plane and a line, first the line fades out, then the plane fades out. For that I am using the transparency value. The line fades out just fine, but I am having problems with the plane. I set a key frame with the transparency value at 0 in the frame 260:

And then I set another key frame at the frame 320, with the transparency value at 1.

enter image description here

But the plane is still there, still visible, I do the same with the line and it works fine. What am I doing wrong.

    $\begingroup$ Could you upload a .blend using BlendExchange. Sometimes we need a bit more information than what can be communicated with images and text. Thanks! :) $\endgroup$ Jun 6, 2016 at 0:37
  • $\begingroup$ Your timeline doesn't show any keyframes. Are you sure you set them? $\endgroup$ Jun 6, 2016 at 0:47
  • $\begingroup$ Yes I set them, you can see them in the Dope Sheet. $\endgroup$

I found out the problem. I had to change the setting in the render properties, light paths, to allow more transparency.
