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

Anonymous — Tue, 24 Oct 2006 12:12:07 GMT

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 don't think you can do that in ArchiCAD Lightworks materials. I think you can do it with Archicad internal engine together with rebuilding the image for each frame of the movie that you render from ArchiCAD. You need to define a material that uses a Quicktime movie that changes colour with time.

The simplest way for me to do it would be to use http://www.strata.com/ as you can change materials over time using the timeline in the project window of Strata. No need for a quicktime movie. I assume other 3d rendering apps can do something similar.
