I started with sculpting on zbrush. then I reduced the number of polygons(Zplugin-Decimation Master). I divided it into 4 parts because my computer is bad.
After the walls were finished, I proceeded to paint small pieces. I worked in 2048x2048 size.
I used 3ds max and vray. I had a problem transferring from substance painter to vray. I just created my account. If I create a blog again, I will be prepared. Thank you for giving a time.
