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