As a novice in 3D object modeling and mod creation for this game, I’d like to seek advice on the following questions:

1.Are there any methods, tutorials, or conceptual frameworks for creating skeletal animations that replicate linkage motion for locomotive models with linkages?

2.When creating building mods, I encountered an issue with night textures displaying incorrectly—specifically, the intended textures fail to load entirely, and the game instead displays textures from other buildings in an abnormal manner. What solutions are available to fix this problem?

3.What methods can be used to calculate a model’s in-game volume relatively accurately, ensuring the model appears at a reasonable size when placed in the game?
