Video game development is full of names that have made groundbreaking steps you’ve never even heard about. Shawn Nash is a behind-the-scenes pioneer responsible for SODA Off Road Racing’s incredible physics, Papyrus’ graphical advancements and iRacing’s use of laser scan data for the physical track surfaces.
This interview with RSC, published in 2021, details his early life and career, through both his own company, Papyrus, Electronic Arts, to his time at iRacing.
As a direct ancestor of iRacing, the ‘Grand Prix Legends engine’ had multiple stock car racing false starts, before eventually releasing as NASCAR Racing 4. The original NASCAR 3, cancelled and replaced by one that used NASCAR 2’s engine, is barely remembered.
Reiza Studios have released an update for Automobilista 2 that includes a number of further AI tweaks to stop cars using grass and off-track areas when seeking a way past the car ahead and brings the v1.5.5.2 tire tread tweaks to other classes.
