Invisible – When enabled, the shape of the light source is not visible in the render result. When disabled, the source is rendered in the current light color. This only affects the visibility of the light when seen directly by the camera or through refractions. The visibility of the light with respect to reflections is controlled by the Affect Specular option. Shadows – When enabled (the default), the light casts shadows. When disabled, the light does not cast shadows. Affect Alpha – Determines whether the Dome Light is visible in the Alpha channel of the render. When enabled, the alpha is white and the background is visible. When disabled, the alpha is black and the background is visible. Affect Diffuse – When enabled, the light affects the diffuse properties of the materials. Affect Specular – When enabled, the light affects the specular of the materials. Affect Reflections – When enabled, the light appears in the reflections of materials. Texture Resolution 1 – Specifies the dimensions at which the texture is resampled for importance sampling. Textures attached to the Color/Texture HDR slot are controlled only by the Texture Resolution parameter and ignore the GPU Texture mode. Minimum texture size for Dome Light by default is 2048 and cannot be set lower. |
Caustic Subdivs – Controls the amount of photons that V-Ray traces to estimate caustics. Lower values produce noisy results but faster rendering. Higher values produce smooth results but take more time. Target Radius – Defines a sphere around the light icon where photons are being shot when photon-mapped caustics or global photon map are used. Emit Distance – Defines a sphere around the light icon from which photons are being shot towards the target radius area. |
