How to make a material that changes colour by sunlight AC10?

[Anonymous]

I've been searching for the option in archicad 10 to make a material (in 'material settings'), that changes from colour, during the day...
what i want is a facade that react on the sunlight and position of the sun during the day > so the colour will change in time...

for an example: check the building 'la defense' from the architectural office 'UN Studio' in Holland

Maybe someone knows how to set the 'lightworks shader settings' to realise my idea...? i've been trying an searching for a long time, but i didn't found the solution yet.

i've asked this question in 'working with archicad' as well. i did get an answer, but i'm hoping for a solution in archicad, without using other programs like strata 3d...
off course, if it's not possible i will try it with an external 3d-program

I don't think what you want to do is possible in Archicad.

While assigned metamerism is not possible with LightWorks, the poster might have success using a facade assembly that includes a screen with tiny tilted bands. As the sun gets lower in the sky, the underside of the shaded bands will brighten to provide the change effect. A scrim....

Besides, what's the problem with just changing the material to suit the design vision at any given time of the day?

If this is for an automated sun study, I believe it possible to script material changes (GDL gurus please clarify) during the generation of the fly-thru.
