I love how easy it is to get things done in spline. Still a drastic learning curve for non 3D folk. They have some good tutorials, but they are way too fast for a beginner to keep up with and way to basic for an advanced user to find interesting.
Excited! Spline is truly breaking new ground with its emphasis on LUI (Natural-language user interface) for design tools, which is undoubtedly the future of democratizing access to powerful software. Congrats on the product launch!
A revolution in the accessibility of high-quality real-time 3D in the browser for everyone. I can't remember the last time I opened Cinema 4D or Blender. Only the new Unreal Engine might shake this trend.
