What developers are saying

  • The trueSKY package allowed us to add gorgeous, dynamic sky and clouds to State of Decay 2 within our strict performance parameters, and truly helped bring the world of State of Decay 2 alive.

    Jeff Strain, Studio Head, Undead Labs

  • trueSky from Simul is one of very high quality and outstanding technology to 3D games. Their weather system just bring a life into a game. Truly true Sky it is. Also their hands on integration support is very helpful. Depending on the level of demands from my customer, Simul has always given the best possible support and suggestions in very good timing manner.

    Yoshikazu Furuhata, CEO, IGM KK

  • Our ongoing goal for Flight Sim World is to look for ways in which we can advance flight simulation beyond the types of experiences available today. Simul’s trueSKY offered the kind of leap in weather and sky technology we needed in order to make this happen.

    Stephen Hood, Executive Producer, Dovetail Games

  • Motocross is feeling your bike in off road and wild contexts. Achieving this result in a video game is really challenging because you want the environment to look alive. TrueSky allowed us to ride across our compound areas with seamless variations between sun, rain and clouds, bringing a whole new level of realism in our motocross experience.
