Project: A game engine embedded in to 3ds Max. (Similar to Blender Game Engine)
Goal: Creating an artist friendly game and interactive application development environment in 3ds Max.
This is a "working in progress" project. We develop both a plug-in for max to syncronize max scene with our game engine and also game engine it self. In the end, we have seen that 3ds Max become a nice WYSIWYG editor for our game engine and the project is doable with the 3ds Max SDK.
We think that the idea has some potential espacially for 3ds max users but we are a small team so we are considering to move on an open source engine, URHO3D and bring this idea to life.
Your thoughts and comments are very welcome.
