I worked on a spacecraft for a personal project for the last couple of days. This was my first attempt at creating something like this. I used Blender for modeling, Substance Painter for baking the details from the high-poly to the low-poly mesh and for texturing the whole spacecraft. For rendering I used Unity 5.4 and Marmoset Toolbag.
The whole spacecraft has 25,268 tris. Feel free to share your opinions.
