Does somebody know what the problem is with the "T" in producTion in this video http://www.youtube.com/watch?v=KIXtBTOkgjg

Looks like Z-fighting

You have duplicate faces in there somewhere, and they are 'fighting' to be the on top. In fact, it looks like you might have two 't's right on top of each other.

Thanks for responding
And how can I solve this??

You need to delete the duplicates.

There are many ways to do this, depending on how your model is setup.

Try selecting the entire 't' in Edit Mode and then 'remove doubles'.

If there is an entire duplicate 't' which is also a different object, that will not work. In that case you will need to delete one of the two objects.

But there is only 1 object and 1 letter T

If there is not a hidden duplicate causing it, I do not know what to tell you.

You could upload the .blend file somewhere, and I could take a look at it if you want.

Sorry for the delay.

Yes, it is definitely z-fighting.

I didnt think to ask if you had left the text as a text entity instead of converting it into a raw mesh. If you convert all of your text to mesh ( Alt-C ) you can them remove doubles and the flicker goes away.

Might also save you some render time.

Thanks so much Tehrasha, it works!!
