[7] The Blend4Web toolchain consists of JavaScript libraries, the Blender add-on, and a set of tools for tweaking 3D scene parameters, debugging, and optimization.
[9] In October 2019, an "Absolutely new Blend4Web"[10] was announced, planned to make developing 3D apps easier and to add a new marketplace where people can offer their 3D models.
The speed and the direction of animation (forward/backward play), as well as particle system parameters (size, initial velocity, and count), can be changed through the API.
[13] Some out-of-box options exist for rendering extended outdoor environments, including foliage-wind interaction, water, atmosphere, and sunlight simulation.
One example demonstrating these effects is "The Farm" tech demo, which also features multiple animated NPCs and the ability to walk, interact with objects and drive a vehicle in first-person mode.
[23] The following post-processing effects are supported: glow, bloom, depth of field, crepuscular rays, motion blur, and screen space ambient occlusion.
[30] Blend4Web supports a set of Blender-specific features such as the node material editor (a tool for visual shader programming)[31] and the particle system.
[34] This Blend4Web-based app[35] makes it possible to operate the rover, control its cameras and the robotic arm, and reproduce some of the prominent events of the Mars Science Laboratory mission.
