I have a very very simple animation where I have to fade out a mesh, from a complete opacity to zero. How do I achieve this?

In the materials tab of your mesh, add a new material if there is not one already. Then, scroll down until you find the transparency tab. Enable transparency, and you will see a slider that allows you to change the opacity (or transparency) of the material, and thus, the mesh. I would use z-transparency as it is the most realistic.

With the opacity set to full, choose the frame when you want to begin the fade, put your mouse over the opacity slider I. Then, move to the frame when you want the mesh to be transparent, slide the opacity slider to 0 and hit I (with your mouse over the slider) again.

This technique is for blender internal

  • $\begingroup$ THank You, just done - but if I play the preview, will I see it fading out? Do I have to render the animation to see the effect? $\endgroup$

  • $\begingroup$ I tried as you said some 2-3 times but I cannot see it from the animation player $\endgroup$

    $\begingroup$ By animation player, do you mean the viewport? If you use rendered shading in the viewport (it's in the same drop down as solid and wireframe in the latest version of blender), and then advance frame by frame through the animation, I believe you can see the change in the viewport. However, you could also just render one frame in the middle of the transition to make sure it's working $\endgroup$

    $\begingroup$ If you enable Transparency in Properties > Object > Display with the object in question selected, it will be visible in solid view as well. $\endgroup$
