The best part about it was its ability to render huge amounts of models in one go, which helped us with rendering out large volumes of assets (like buildings). I didn't like how slow it would get when using multiple GPUs; not because it wasn't powerful enough but more so due to some issues with drivers. Corona has been used by our team since we started working on building games back in 2013. We were able to create realistic environments without having to rely heavily on external tools such as Unity or Unreal Engine.
