Scale of a 3D project.

I dont want to sound silly but could someone explain me at what scale a 3D artist works when deaing with an archviz? Size of the terrain and everything? Should be at the real scale if using biased rendering or this only works with unbiased rendering?

1:1 real world size. it sort of matter if you use m, mm , feet or inches. ie if you are modelling a huge city then you'd use meters but if you were doing product shots of a perfume bottle you'd use mm.

CAD and CADlike stuff should be done at 1:1. Because... why not? The only reason things used to be drawn at 1/4" or whatever was because real buildings don't fit on small pieces of paper. There is no small piece of paper in the computer. Having to translate between 12-3/16" to 37'-2" wasn't something people wanted to do. Now if you have a wall that's 37'-2" long you just... make it 37'-2" long.

 

AND... Modern correct lighting solutions only look right if they are 1:1 because light doesn't behave the same in a shoebox as it does in a stadium. Old school stuff, scanline renderer, basic ray trace, standard lights... all that stuff could work at arbitrary scale because we just tried to make it look good.

You should always be modelling at 1:1 scale.

Thanks to all for the answers.
