Light conducting grid…

[Mylenium]

[max_iqueu] “Would there be a way to do something with Expressions or any other way for the grid to
only be effected by the highlights of the fractal noise background?”

Expressions cannot acces pixel data. What you have to do is tu unmultiply your Fractal Noise using XMult or similar tools. Once it has Alpha information, it’s much easier to tweak it.

[max_iqueu] “Would there be an efficent way to really make the light particles follow the grids path?”

Not in AE. You need a 3D program for that. Depending on what you are rtrying to do, you may get some simplistic stuff using Trapcode’s Particualr with the Path mode, but everything else is really not for AE.

Geomancy from digital Anarchy might do the trick for you.

Yes, You are so right. Completely forgot. Grid Lines may work.

Thanks you very much, that really helped.

The plugin is even affordable @ 99US$
I’ll give it a test run and see what it looks like.

Is there a way to xMult within AE?
How can I create an Alpha Mask within AE? Only by rendering?

Mylenium, would you mind explaining me “unmultiplying”, please?

Many thanks for your help again,

Here’s what I’d do:

Create a medium-blue grid

duplicate the grid layer.

Set the top layer to the Add blending mode

add the fractal noise effect to the layer on top

Set the fractal type to strings

Set the EFFECT’S blending mode to Darken

Set the Effect’s contrast to a very high number

Set the effects Brightness to a low or negative number

Animate the effects evolution and/or transform properties

Add the glow effect and set the glow threshold to very low (You might want to do this earlier so that you can see things a little better

(Alternatively, to this last step, you could change the grid effect’s color to a brighter color and add a blur effect).

That should do it.

Hello Aharon,

many thanks for your “How to…” I tried it out already and it works just great.
I actually used an adjustment layer as the base. Don’t know if that causes problems later on… I guess to top it off, a little Motion Blur and the result will be stunning – for me anyway.

Do you think there is a way to eliminate the grid structure completely? I didn’t really manage. I guess I could use another contrast effect ontop of it? But I’m thinking: there must be a more elegant way?

Off topic:
Many thanks also for your AE-Podcasts. It really helped me to find my way round AE much faster. It’s not just what you’re actually explaining but all the little workflow things around it, that make it so interresting. And fortunatly it’s not as “stiff” (as in: uptight) as the Ad*be training DVDs.

Best,

/Harald

Hi there-

I think you could get rid of the grid structure if you approached the porject from a different perspective. Create a grid, and then create another solid layer with the same fractal noise effect. Use that fractal noise effect as a Luma matte for the grid layer, and you will only see the parts of the grid that fall under the whiter parts of the fractal noise. Then either add an adjustm,ent layer with a glow effect, or nest the comp in a new comp and add the glow effect to the nested comp.

I’m glad my training is helping you.
