Perhaps this is a good time to think about the future of dim3 in general.
The last few days have been very eventful for the indie game community. Three major game engines, UE4, Unity 5 and Source 2, are now completely free. Dim3 used to be the only free game engine for Mac. That was what made it unique and gave it a purpose.
Now you can choose from a number of free solutions and each one beats dim3 in every way imaginable. Why would anyone still pick dim3 when they could be using the same tools that were used to make some of the most amazing games of the past two decades?
I just don't see that happening.
Do you plan on keeping the development going? If it's a hobby, that's perfectly fine of course, but you can't expect people to actually use dim3 for anything. I personally would find that very discouraging.
Maybe it's time to move towards a different goal. Auto-generation of content is certainly a possibility and especially in rapid prototyping its very useful. Perhaps a library that could be wrapped in Plug-Ins for all major engines would be a nice project that's not only fun to develop but also gives the game development community a useful tool, which dim3 is not.
Again, I'm not saying you should stop developing dim3. All I'm saying is that I would, if it was my project.
