Light animation through grasshopper

Hello

Good day

Does anyone have a clue about animating lights (vray / other render engines) through grasshopper?

I'm trying to produce an animated visualization of the steps of a staircase that light up when you step on them.

Each time some one steps on it, it creates a wave of light that ends up fading in the last step of the staircase everytime weaker.

So need to link a light that increases and decreases in potensi, all conected working in unison according to the distanse of a attractor

Sorry for my english

Thanks!

I just need any kind of visual representation that would deal with the stair case and user position to make the whole thing understandable.

Please help

You can do this. take the center of each step surface. Put an attractor on the step you are standing. Give the stairs a gradient swatch based on the attractor values that goes from bright to dim. Cull the colors outward from atttractor in a loop via hoopsnake.

If you need true light emission, you can create (and animate) emitter materials for Maxwell Render with Scarab.

What do you mean with?

Cull the colors outward from atttractor in a loop via hoopsnake.

Loop the culling pattern from attractor point out with hoopsnake. So first you cull all but the step your on. Then you cull all except the step behind and in front of you and so on.
