	Defining industry tiles follows the same schema as houses do: to start using an ID, you first need to define it by setting property 8 for it. If you try to reference an ID (either via action0 or via action3) that isn't defined, your request is ignored, but not reported as an error, either. This means that if you want to conditionally define an ID, all you need to do is skipping the action0 that sets property8, and everything else gets skipped automatically.		Defining industry tiles follows the same schema as houses do: to start using an ID, you first need to define it by setting property 8 for it. If you try to reference an ID (either via action0 or via action3) that isn't defined, your request is ignored, but not reported as an error, either. This means that if you want to conditionally define an ID, all you need to do is skipping the action0 that sets property8, and everything else gets skipped automatically.

	Industry tile IDs are unique within each grf file~~. The per-GRF ID is specified as a byte, which means no GRF can define more than 256 tile IDs~~. You should use your industry tile IDs sparingly. [[VariationalAction2/Industry_Tiles#Relative_position_.2843.29\| Variational action 2 variable 43]] for industry tiles can help you limiting tile consumption to 2 or 3 per industry. Avoid using tile FFh, so the tileID can be turned into an extended byte (in Action 3) in the distant future without breaking your NewGRF.		Industry tile IDs are unique within each grf file.

			If bit 4 is set to activate callback 2F, the game will not automatically attempt to level the land around this tile when building a new industry.
