Overview
The V-Ray Dome Light is a V-Ray specific light source plugin that can be used to create physically accurate area lights.
Rotating the viewport Dome Light widget affects the Dome projection on all 3 axes.
Settings
Enabled () – Turns the V-Ray Dome Light on and off.
Color/Texture HDR – Specifies the color of the light. When using photometric units, this color is normalized so that only the color hue is used, whereas the light intensity is determined by the light Intensity. Specifies an HDRI or texture file for the V-Ray Dome Light, and enables or disables it. The texture intensity is also affected by the Intensity of the light.
Textures attached to the Color/Texture HDR slot are controlled only by the Texture Resolution parameter and ignore the GPU Texture mode.
Intensity – Specifies the strength of the light.
Units – Specifies the light unit of measurement. The light will automatically take the scene units scale into consideration to produce the correct result for the scale being worked in.
Default (Scalar) – The color and multiplier directly determine the visible color of the light without any conversion. The light surface will appear with the given color in the final image when seen directly by the camera.
Luminous Power (Lumens) – Total emitted visible light power measured in lumens. The intensity of the light will not depend on its size. A typical 100W incandescent light bulb emits about 1500 lumens of light.
Luminance (lm/m^2/sr) – Visible light surface power measured in lumens per square meter per steradian. The intensity of the light depends on its size.
Radiant Power (W) – Total emitted visible light power measured in watts. The intensity of the light does not depend on its size. This is not the same as the electric power consumed by a light bulb for example. A typical 100W light bulb only emits between 2 and 3 watts as visible light.
Radiance (W/m^2/sr) – Visible light surface power measured in watts per square meter per steradian. The intensity of the light depends on its size.
Luminous Power (Lumens) – Total emitted visible light power measured in lumens. The intensity of the light will not depend on its size. A typical 100W incandescent light bulb emits about 1500 lumens of light.
Luminance (lm/m^2/sr) – Visible light surface power measured in lumens per square meter per steradian. The intensity of the light depends on its size.

Radiance (W/m^2/sr) – Visible light surface power measured in watts per square meter per steradian. The intensity of the light depends on its size.
Shape – Specifies the shape of the Dome light as either a sphere around the scene or only a hemisphere.
Texture Resolution – Specifies the dimensions at which the texture is resampled for importance sampling.
Use Transform – When enabled, the HDRI texture locks to the orientation of the V-Ray Dome widget and allows them to rotate together in the scene.
Options
Invisible – When enabled, the shape of the light source will not be 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.
Affect Alpha – When enabled, the virtual sphere on which the dome texture is mapped is visible as a solid object in the rendered image's alpha channel.
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 reflections of materials.
Shadows – When enabled (the default), the light casts shadows. When disabled, the light does not cast shadows.
Caustic photons
Caustic Subdivs – Used by V-Ray when calculating Caustics. Lower values produce noisy results but will render faster. Higher values produce smoother results but take more time.
Target Radius – Defines a sphere around the light icon where photons are being shot when photon-mapped caustics or the 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.
Notes
- Left-clicking the Dome Light V-Ray toolbar button leads to creating a Dome light at a specified point, and right-clicking – as a spherical dome light. These options are also available in the vrayLightDome command.

Light & Rusty Texture Pack
Light Weight Texture Series
Light Weight Texture Series
A very ram-friendly texture series taken from real source, a rusty barrel.
Every texture is created in Adobe Illustrator, optimized and reduced to their minimum of anchor points but the real secret are the included tiff textures!
Every texture is created in Adobe Illustrator, optimized and reduced to their minimum of anchor points but the real secret are the included tiff textures!
Simply drag and drop or place the tif texture on top of the design and change the color like you’re used to it in Illustrator. Instant result, no “beachball”!
Bonus: Every texture as no-edge / smooth-edge high-resolution Photoshop .abr brush. Simply load brush file via brush panel and texture on!
What’s included in the Pack:
32 TIFF textures (bitmap-tiff)
1 ABR Photoshop brush file (CS6-CC) with 32 brushes
2 AI files (CS6-CC) with a vector file of every texture
32 PNG files
1 layered PSD file
