Is there any way to animate custom models for mobs using Cubiks java format?
I have done a search for modelers/animator software that exports to .java most will export as .obj files or other formats.
Maybe you can make a built-in animator using pivot points and a time bar to add animations upon moving the model pivot points at a set time.
Sony Movie Studio Platinum 13 has a similar animation setup and its extremely easy to animation the videos you could use the same system to mark model locations at current time frames. I think it would be a good idea to eventually add built-in feature for modeling editing into the program so that people don't need to find third-party tools to make their mods that way doing things can be universal if people wish for help and it can also ensure that programs will always be available if for whatever reason a particular program was used and widespread support in the community gets taken down there will always be an option on MCreators end that people can use.
Just an idea and some feedback from what I have seen, this would be more of a long term goal than an over the night next update feature, and I am very aware of that but please consider what I said about having your own tools.
We have in plan to make better support for animations, but build in animator with 3D preview is most likely a bit over the head of current MCreator and resources we have. If things change, we will definitely consider this one.
