I'm working on some motion graphics that involves making text appear from behind objects and other text.

I was able to get the first word appear correctly using empties, texture mapping, and mix shaders. (I've been following this tutorial.)

However, when I attempted to use the same method, the second word ends up looking like this:

Does anyone know why this is/how I could fix it? I want the second word (Tech) to disappear/appear behind the first word (VES in the screenshot).

Materials:

  • Background surface is a plane set to Emission, Strength 2.0
  • First word (VES in the screenshot): Text object, node setup: enter image description here
  • Second word (Tech in the screenshot, static-y): Text object, node setup: enter image description here

    $\begingroup$ It seems like Z-fighting (related question), which occurs when both words are semi-/visible. Are the letters located on top of each other? $\endgroup$

  • $\begingroup$ @MrZak Yeah, that's kinda what I was thinking. And yes, they are on top of each-other $\endgroup$ Commented Dec 21, 2015 at 20:45
  • $\begingroup$ @stacker Yeah, that's my issue. Is there no way to fix it? $\endgroup$ Commented Dec 21, 2015 at 21:07
  • $\begingroup$ @stacker But the thing is that I need the text to slide out from behind the first text object. I've updated my question. $\endgroup$ Commented Dec 21, 2015 at 21:18

    $\begingroup$ @RPiAwesomeness Just move one of the text objects slightly along the y-axis. so that they don't overlap exactly. $\endgroup$

Both text objects are located at exactly the same y-coordinate (0). To fix this move one of the text objects slightly along the y-axis after that the z-fighting artifacts will disappear.
