Our team is glad to present a new release of Blend4Web, an open source tool for developing interactive 3D web applications. In this release you will find: the node-based logic editor, support for multiple "Material" nodes in node materials, tools ported to Windows, support for the brand new browser Microsoft Edge and new APIs for parent-relative transforming. We also present a new demo app with this release - a large-scale visualization of a real manufacturing enterprise.
