 - The BlueMap plugin has a command `/bluemap debug` that shows you all the information BlueMap has about the block at your feet and the one you are standing on. For 1.12.x this also includes the numeral-id and the meta-value.

+So this is pretty simple. To render blocks correctly, BlueMap needs to know if a block is:
+- `culling` it's neighbor block-faces: If the neighbors block-face that is facing this block [can be removed](https://en.wikipedia.org/wiki/Hidden-surface_determination#Occlusion_culling) because it is not visible.
+- `occluding` near blocks: This is basically used to determine if the block is "occluding" light when calculating the [ambient occlusion](https://en.wikipedia.org/wiki/Ambient_occlusion) on neighbor blocks.
+- is `flammable`. This is currently only used in 1.12.x to calculate the appearance of fire.

+If there are no properties defined for a block, BlueMap looks at the model and "guesses" its properties. This is mostly pretty accurate, but you can configure it in this config if you need to.
