Hi there!
Today, I've finished this insane building update and exported everything from 3d editor to Unreal, fixed the materials and a few broken things. Broke building upgrades, but that's okay. Wow. I started to think that this whole "I'll remake every building in three upgrade levels" process will never end.
So, now I need to fix the upgrades, add some basic functionality to the new buildings and improve the map generation. The last thing was not planned for the next patch, but I've got an idea of how to make it quite fast and drastically improve the replayability.
So, moving forward with everything. Still to ETA of the next update, but I hope from now on everything will be faster, because I can actually switch back to the programming (which is my main specialization) from Blender :-)
Stay tuned!
