here another course and another industrial scene...
yes its rendered with mental ray. but a lighting like this can also be achieved with unreal engine.
the scene is not optimized with ~50000 tris. but lots of instanced geometry. and the overall tricount can easily be reduced to 30000.
these are all tileable maps
for sure i pimped it after the lecture and i will still change some things in it for a final picture. there are lots of flaws in it
