My role as an Environment artist on The Old Republic is to build worlds. For this level, this consisted of: set-dressing, terrain sculpting and vertex painting, terrain painting (including rocks and flora) lighting, VFX placement, level polish and optimization.
For this level, the train cars and environment was set up by designers to fit with the encounter spawning, and it was my job to set-dress and light everything on the train cars.
All assets were created by other artists. Special thank you to, Carrie Meade, Jason Moulton, Catherine Farinas and the rest of the SWTOR team.
