How to blend between textures easily using nodes? So, I have a system that basically allows me to blend several images together over time.

However, it is a horrible system.

There are keyframes tightly packed keyframes all over the dope sheet.  Here is it:



I manually wrote a GLSL shader to do this with OGRE3D back in the day,  could I plug that into blender?  I may have lost the code...

Thanks in advance.
Sure there is a simpler setup, you can exploit math nodes to do really cool stuff. What I think you want to do is to blend between all 3 textures but using only 1 animated property:





Here I used colors instead of textures but it is the same thing. You can also expand this setup for more than 3 inputs and still having to animate only 1 value.
