This is the last frame from my animation test about a scary effect in Blender. The idea is that a daylight scene changes into a night scene + a text appears on the wall, like it was blood flowing out of the surface or just simply appearing.

The rendertest is here:

I might do a tutorial on the effect, and if somebody could tell my why animated values dont update in real time, i could make the effect work in real time with glsl for the game engine as well (i was intendet to do that, but its not updating the values unless i constantly click on the texture layers).
