Sorry, but I'm a bit of a scripting noob....

I want to know what would be the best way to link the colour of an object to its z-position....

I have tried to wire the parameter, but I need to convert the z-position from a 'float' to an integer (I think).... and I don't know how....

The alternative is to write a script that reads the z-position frame by frame, and then assigns a colour key frame by frame for the material...

Any Ideas / suggestions appreciated!

Thanks....

How about a Falloff map instead? Or perhaps Fog? I'm probably being too simplistic here...

Hmm, I'd use wiring as its the simplest and fastest solution. Have you tried using "my_param as int" ?

You could wire it, but you wouldn't get the level of control that you could get from scripting or using expressions.

Well... I've managed to work out how to write an expression to control the colour of the object :-

box-z_position --> box-material-diffuse-color

using the line :-

(color (z-position/100) (z-position/100) (z-position/100))

as the "Expression for Diffuse_color"
....

That's my first successful bit of wiring using an expression!.... whoopee! :scream:

Cheers
