* Currently, bloom `intensity` and `strength_factor` affect volumetric
lighting `strength` and vice versa. This behavior is to be changed
in the future, do not rely on it.
* `vision_effects`: is a table that controls vision effects
* `color_transform_matrix`: is a matrix with default value (identity matrix):
* `color_transform_matrix`: is a matrix with default value (identity matrix):
```lua
{ {1.0, 0.0, 0.0}, -- r
{0.0, 1.0, 0.0}, -- g
{0.0, 0.0, 1.0}} -- b
```
* Work as `transformed_color_RGB = color_transform_matrix * color_RGB`
* Can be used for creation color blind effect, base for night vision effect etc.
* Work as `transformed_color_RGB = color_transform_matrix * color_RGB`
* Can be used for creation color blind effect, base for night vision effect etc.
* Request client with protocol version 49 or higger.
