I'm pretty much exactly back to par in 1.10.2.
My tile entities render, dynamically, through .objs. Even better, they render in-inventory and in-hand dynamically as well.
Otherwise, I have rotatable, colored machine blocks, beams still render like before, as do particles.
The end result is that rendering works, and from a certain point of view, works better than it did in 1.7.10.
Will continue to work on gameplay mechanics, but I have a very small initial goal set. After I get everything working there, I will continue to expand (similar to Femto 1, but with actual mechanics in mind.)
