Detailed Description▲
QEnvironmentLight uses cubemaps to implement image-based lighting (IBL), a technique often used in conjunction with physically-based rendering (PBR). The cubemaps are typically expected be based on high dynamic range (HDR) images, with a suitable OpenGL format (such as RGBA16F) that can handle the increased range of values.
There are a variety of tools that can be used to produce the cubemaps needed by QEnvironmentLight. Some examples include
HDRI Haven provides many CC0-licensed HDR images that can be used as source material for the above tools.

Notifier signal:
-
void irradianceChanged( *environmentIrradiance)
specular : Qt3DRender::QAbstractTexture*▲
Holds the current environment specular map texture.
By default, the environment specular texture is null.
The exact meaning and use of this property is up to the material implementation.
