i started adding tiles today, and the fully horror of 3d tiles in unity hit me all at once. so many gameobjects, the program crashed four times, oh man. so i ended up telling one of our 3d artists we needed to pivot to using a texture with a normal map instead, and he was actually quite alright with that. the result was MUCH easier to manager, even though it sacrifices being a cool 3d model for being a slightly cheaper looking alternative.
still could be getting more done in the day, but i basically had a headache all throughout today.
