This question already has an answer here:

I'm a complete newbie and was wondering if I had set up something wrong.

I used the 20th Century fox blend and successfully rendered 600 jpg images. Looking good, except that about 30% images have a corrupt T in "Century".

I've spent several hours going through about 200 frames trying to smooth the error out with Gimp. Just wondering what cause the fault and if there is any way to correct it a bit quicker.. Little t bad

Big T bad

  • $\begingroup$ go into the text and select all polygons and Ctrl + N to recalc normals. $\endgroup$ – Vader Mar 30 '14 at 12:20
  • $\begingroup$ You may have some overlapping faces (non manifold objects)... You should check the topology. $\endgroup$ – Polosson Mar 30 '14 at 14:02
  • $\begingroup$ Looks like there is a youtube answer. I'm trying it now.. Right click on the text, Alt+C and click on Mesh from text. YouTube clip So it looks like I can do it that way after all - Thanks Rendering now. so will tell you the outcome in 8 hours..... 6 hours later and 3/4 the way through and every image is perfect. After the camera stopped moving in the original, the fault disappeared anyway, so I know the rest of the sequence is going to be excellent. Cheers guys! $\endgroup$ – user165631 Apr 1 '14 at 9:18

It looks like a topology problem. You can convert the text to a mesh (Alt +C) and try the following. - Recalculating the normals (enter edit mode, select all, Ctrl+N) - Check for non-manifold geometry (edit mode - vertex mode, make sure nothing is selected then Ctrl+Alt+Shift+M) - Remove double vertices (edit mode, W - remove doubles)

If you would prefer to keep the text object, go to the object modifiers tab in the properties window, then try the following:

  • add a decimate modifier
  • set the type to planar

  • $\begingroup$ Sorry, this question will probably frustrate you, but but I click on the text,and press tab to to enter edit mode, then how do I select all? (I thought I'd just press A, but CTRL N just asks to reload file..) $\endgroup$ – user165631 Mar 31 '14 at 10:14
  • $\begingroup$ Nope, I made a bad assumption, you're still using a text object, not a mesh so the given solutions won't work. I've updated my answer. $\endgroup$ – user2699 Mar 31 '14 at 17:32
  • $\begingroup$ Hmmmm.I've not got a properties tab.. My version is 2.62. Is this where I'm going wrong? Still can't select all anyway.. $\endgroup$ – user165631 Apr 1 '14 at 0:52
  • $\begingroup$ The properties window is the one you can select materials, font type etc. The modifiers tab has an icon of a wrench on it. $\endgroup$ – user2699 Apr 1 '14 at 1:02
  • $\begingroup$ In the "Select" drop down menu there's no polygons, and in the modifier menu there's no decimate, so I might be using a previous version of Blender. $\endgroup$ – user165631 Apr 1 '14 at 8:01
