I have managed space ground segment and aeronautical projects for a long time, with up to 45 software engineers. 3D modeling, environment design and animation has begun as a leisure and has quickly become a passion. In this context, I have used several applications: 3D Studio Max, Vue d'esprit, Poser, and now Unity. With Unity scripting, I have seen an opportunity to accelerate the environment creation process. My first project was to automate the building of bridges that fit the terrain. Other projects with the same principles will come soon.
