Dear friends!
As we promised, this year we are planing to organise an important event for our ever-growing community - the first Blend4Web Conference in history. At this conference you will enjoy many interesting presentations by Blend4Web developers, community members and companies. Here you can also meet like-minded people from around the world, showcase your work and get answers to any questions you may have.
We have also released Blend4Web 16.01 recently which includes API for line rendering and new nodes for the logic editor. In addition, we simplified the SDK installation and improved the Head-Mounted Display support.
