Experienced Unity Environment Artist Needed for Alpine Winter Environment
Solid delivery on a complex specification of a 1km by 1km Unity scene in a wintery mountainous region with many assets throughout the map. Very strong communication and checking in on a regular basis. Good balance of technical and artistic skills. What impressed me most is the team's commitment to continue working against a milestone to deliver to a good level of quality. At a couple points i found a few issues in the scene and they worked diligently to ensure the issues were resolved. I would recommend this partner for your complex scene development needs.
