its time to testing lights, it my favorite part 😀
i did so many test for the lighting with hdrs and at last i choose daylight. i know dusk is good too but my concept is playing with light and shadow. and daylight is a great way to create great shadow for the elements of facade, which i wanted to have.
based on search of daylight in Stockholm on the web, i realize that the shadow of sun is a little bit soft.and maybe i can say its cold 😀
so i edited my hdr file in raw plugin of photoshop, to have more light and catch that soft shadow.
here is two simple tests for the dusk and daylight.dusk is only change the hdr without any tuning.

this part is very important, i want to have a realistic texture for the ground, i don’t like use a ready texture and do simple uv mapping, as we can see in google images the texturing of ground is complex. so i have to do unwrap for that, before that i should do some fixing for the model because unwrap needs a clean geometry, some times i use zbrush or maya for retopo and uv of complex models, but this for this i used 3d max unwrap and exported into photoshop, so i could do anything that i want,
after creating base texture in photoshop, i added another coat layer for creating dirt. actually most of elements and materials of this project have dirt. i used a coat layer and add mask to create specific dirt.it takes time but it was necessary.
here we can see process of creating ground.
