Effect "Ambient light"
A light that illuminates all objects from every direction. Often used along with a Directional light (though a Hemisphere light can be used instead of an Ambient light).
This effect is for 3D layers only.
Properties of this effect are:
- Light color. Default value is
255;255;255. For events, write:"color". - Intensity. Default value is
0.75. For events, write:"intensity".
Effect "Bloom"
Apply a bloom effect.
This effect is for 3D layers only.
Properties of this effect are:
- Radius (between 0 and 1). Default value is
0. For events, write:"radius". - Strength (between 0 and 3). Default value is
1. For events, write:"strength". - Threshold (between 0 and 1). Default value is
0. For events, write:"threshold".
Effect "Brightness and contrast."
Adjust brightness and contrast.
This effect is for 3D layers only.
Properties of this effect are:
- Brightness (between -1 and 1). Default value is
0. For events, write:"brightness". - Contrast (between -1 and 1). Default value is
0. For events, write:"contrast".
Effect "Directional light"
A very far light source like the sun. This is the light to use for casting shadows for 3D objects (other lights won't emit shadows). Often used along with a Hemisphere light.
This effect is for 3D layers only.
Properties of this effect are:
- Light color. Default value is
255;255;255. For events, write:"color". - Distance from layer's camera. Default value is
1500. For events, write:"distanceFromCamera". - Elevation (in degrees): Maximal elevation is reached at 90°.. Default value is
45. For events, write:"elevation". - Shadow frustum size. Default value is
4000. For events, write:"frustumSize". - Intensity. Default value is
0.5. For events, write:"intensity". - Shadow casting. Default value is
false. For events, write:"isCastingShadow". - Shadow bias: Use this to avoid "shadow acne" due to depth buffer precision. Choose a value small enough like 0.001 to avoid creating distance between shadows and objects but not too small to avoid shadow glitches on low/medium quality. This value is used for high quality, and multiplied by 1.25 for medium quality and 2 for low quality.. Default value is
0. For events, write:"minimumShadowBias". - Rotation (in degrees). Default value is
0. For events, write:"rotation". - Shadow quality. Default value is
medium. For events, write:"shadowQuality". - 3D world top. Default value is
Z+. For events, write:"top".
Effect "Fog (exponential)"
Exponential fog for 3D objects.
This effect is for 3D layers only.

0.0012. For events, write:"density".
Effect "Exposure"
Adjust exposure.
This effect is for 3D layers only.
Properties of this effect are:
- Exposure (positive value). Default value is
1. For events, write:"exposure".
Effect "Hemisphere light"
A light that illuminates objects from every direction with a gradient. Often used along with a Directional light.
This effect is for 3D layers only.
Properties of this effect are:
- Elevation (in degrees): Maximal elevation is reached at 90°.. Default value is
90. For events, write:"elevation". - Ground color. Default value is
127;127;127. For events, write:"groundColor". - Intensity. Default value is
0.5. For events, write:"intensity". - Rotation (in degrees). Default value is
0. For events, write:"rotation". - Sky color. Default value is
255;255;255. For events, write:"skyColor". - 3D world top. Default value is
Z+. For events, write:"top".
Effect "Hue and saturation"
Adjust hue and saturation.
This effect is for 3D layers only.
Properties of this effect are:
- Hue in degrees (between -180 and 180). Default value is
0. For events, write:"hue". - Saturation (between -1 and 1). Default value is
0. For events, write:"saturation".
Effect "Fog (linear)"
Linear fog for 3D objects.
This effect is for 3D layers only.
Properties of this effect are:
- Fog color. Default value is
255;255;255. For events, write:"color". - Distance where the fog is fully opaque. Default value is
2000. For events, write:"far". - Distance where the fog starts. Default value is
200. For events, write:"near".
The 3D extension is always installed in all GDevelop projects: there is no need to add it from the Project Manager.
