Have you heard about FlowScape? It is an app that lets users create their own nature scenes simply by painting.
The toolkit provides 20 landscapes and more than 300 models to create scenes by painting trees, changing the sky, rotating the sun, adding sound effects and adjusting a camera.
There’s an intuitive interface, an ever-growing community, and free content updates. The toolbar features advanced paint options such as align to landscape, size, the flow of the brush, random leaning, grow speed, and layers to determine where things get painted. You can drop objects such as rocks, logs, twigs and leaves using real-time physics to set up scenes.
Well, it’s not a full-featured game engine or a 3D modeling app, but that’s a nice way to play with 3D scenes if you lack essential skills and just want to have fun. You can learn more and get the app on Steam.
