yes i know and thets the reason every architectural visualisation looks allmost the same. I know ive done work with architects.
Anyway, its niot actualy true theyd want it so its jsut a lazyness thing. Wood does not look like wood every single wood surface looks different. But some architects have a wierd onlook that wood is wood, and glass is glass. Wich isnt true offcourse.
But also this is why architectural renderings are so expensive to render. Its fine for stills (it does noty much matter if the render takes 1 minute or 6 hours ist still just one image) but once you do the production animation its no longer a good idea.
