I wonder how big the deliverable is compared with Unity, UE4 or other similar solutions? I am a long-time Blender user, but I have never used this in any of its previous versions. It seems it supports a lot of the things from Blender - materials, lights, and others. I will have to see how much can be directly used in the transition. I am not very clear on GPL. If I use it for my company, but I choose to release the source, do I still have to pay for a commercial license or is the open source license adequate? I know the commercial license comes with a lot of support material.
