Thanks Stefano. That works really well. Incase anyone else it doing this, you should apply the expressions as global positions, incase you need to move the spot root null. Also I could only get this to work with the setting of “Distance between V1 and V2″ on the last Vector_math_scalar not the “Dot Product” but works really well. Moving the gradient’’s MINimum Active Range will spread out the center. Also I recommend adding an expression to the gradient’’s MAXimum Active Range like this: Spot.light.LightCone / 120. So when you move the light’’s cone angle, the colors stay relative to the falloff. Thanks for your help Stefano.

I know, you have to do it from the Explorer. Expand the spot node until it shows the vector input, there you have the 3 components editable.
Actually, what I like better in these cases is connecting the node I need to put expression on straight to the root node (in this case the light color, so Xsi will add a vector 2 color converter), so the explorer is easier to climb up. When I”ve set the expression, I restore the initial network. Fortunately, the expressions are kept also if a node is temporarly unconnected.
However, I would really like a “Track Selection From RenderTree” option in the explorer.

Stefano, can you help with the positional expression you”ve entered on the first save state. Only one input node for all three axis… not able to get it to understand the interest’’s seperate xyz… thanks!
