- // Distance around the edge of the camera (in pixels) to draw dynamic occluders. Increase this

- #macro BULB_DYNAMIC_OCCLUDER_RANGE 100
- // Adds an extra triangle for each occluder to compensate for situations where a light might be
- // very close to an occluder. Normally, this would cause light to bleed through the wall. Setting
- // this macro to `true` will solve near-light problems but does incur a slight performance penalty.
- #macro BULB_COMPENSATE_FOR_NEAR_OCCLUDERS false
- // Whether renderers, lights, and sunlight should default to having normal map support enabled.
- // This saves a lot of time setting `.normalMap` on everything that you create. Enabling normal
- // maps has a significant performance penalty so use this carefully.
- #macro BULB_DEFAULT_USE_NORMAL_MAP false
- // The alpha threshold for sprites when drawing to the normal/specular map. Anything below this
- // value will be discarded by the shader.
- #macro BULB_NORMAL_MAP_ALPHA_THRESHOLD 0.5
- // How intense the specular map effect should be. This generally is only noticeable when using HDR
- // lighting. The specular map is packed into the alpha channel of the normal map surface.
- #macro BULB_SPECULAR_MAP_INTENSITY 10.0
- // The default notional "z height" for lights and sunlight. This z value is only used when
- // calculating normal map influence on lights. A lower value brings the light closer to the plane,
- // leading to a shallower angle of attack. This leads to more intense normal maps where the edges
- // of shapes will be highlighted more strongly than the tops of shapes, especially at distance.
