Great monster and the yellow ball is dead! hhehee very cool! thanks for share.

Very informative as always- thank you, Monster!

Just created some homework :wink:

Hey Monster,

Quick question:
Is there any way to change the color of the font/text?

Thanks in advance,

Yes, the color is defined by the Object color. If you change the object color you change the color of the font.

You can do that with an Action (mouse over object color field + <I> to set a keyframe).
Or you do it via Python.

3Q,for your share

WAW thanks for this awesome tutorial
