SFM is a great tool and a lot can be achieved with it, but in its current form the potential is always going to be severely limited.
So we're going to prototype our own film maker made with our C# editor API.
With the recent addition of the IM3D API
we're in a great position to achieve this without needing any C++.
Which means it'd be open-source, incredibly extensible and we could allow community contributions to the tool itself, pushing the potential far beyond anything if we committed to updating the native C++ version.
