Diffuse Diffuse – The diffuse color of the material. Note the actual diffuse color of the surface also depends on the reflection and refraction colors. See the Energy preservation parameter below. Roughness – Used to simulate rough surfaces or surfaces covered with dust (for example, skin, or the surface of the Moon).
For more information, please see the below. Example: The Roughness Parameter This example demonstrates the effect of the Roughness parameter. Note how, as the Roughness increases, the materials appears more 'flat' and dusty. Reflection Reflection – Enables reflection of the material.
Reflection Color – Specifies the reflection color. Note that the reflection color dims the diffuse surface color based on the Energy preservation option. For more information, please see the below. Highlight Glossiness – Enables a separate glossiness control for the specular highlights of the material. Enabling this option and setting the value to 1.0 disables the specular highlights. Reflection Glossiness – Specifies the sharpness of reflections. A value of 1.0 means perfect mirror-like reflection; lower values produce blurry or glossy reflections.
Use the Subdivs parameter below to control the quality of glossy reflections. For more information, please see the below. Fresnel – When enabled, the reflection strength depends on the viewing angle of the surface. Some materials in nature (e.g. Glass, etc.) reflect light in this manner. Note that the Fresnel effect depends on the index of refraction as well.
For more information, please see the below. Reflection IOR – When disabled, the Refraction IOR is used as Reflection IOR.
Enable for finer control over the Reflection IOR. BRDF – Determines the type of BRDF (the shape of the highlight).
The use of GGX model is recommended for metals and other highly reflective materials. For more information, please see the example below.
Phong Blinn Ward Microfacet GTR (GGX) Back Side Reflect – When disabled, reflections are calculated for the front side of the objects only. When enabled back-side reflections will also be calculated. Max depth – Specifies the number of times a ray can be reflected. Scenes with lots of reflective and refractive surfaces may require higher values to look right. Affect Channels – Specify which channels will be affected by the reflectivity of the material. Color Only – The reflectivity of the material will affect only the RGB channel of the final render Color+alpha – Causes the material to transmit the alpha of the reflected objects instead of displaying an opaque alpha.
All channels – The reflectivity of the material will affect all channels and render elements. GTR Tail Falloff – Active only when the BRDF is set to GGX. It allows fine tuning of the specular reflections by controlling the rate at which the sharp specular highlight fades out. Higher values create a value spread out the fade out of the highlight. This parameter does not affect the size of the actual highlight - this is controlled by the Reflect glossiness paramater.
For more information, please see the below. Anisotropy Anisotropy (-1 to 1) – Determines the shape of the highlight. A value of 0.0 means isotropic highlights. Negative and positive values simulate brushed surfaces. For more information, please see the below. Rotation – Determines the orientations of the anisotropic effect in a float value between 0 and 1 (where 0 is 0 degrees and 1 is 360 degrees).
For more information, see the below. Derivation – Determines the anisotropy orientation method. Local Axis – The orientation of the anisotropic reflection/highlight is based on the object's local X, Y or Z axis.

UVW – When enabled, the orientation of the anisotropic reflection/highlight is based on the specified map channel/set. Local Axis – Specifies a local axis used for Anisotropy orientation. (X, Y, Z) Map Channel/Set – Specifies a map channel that is used for the anisotropic reflections/highlights orientation. Dim Distance Dim Distance – Enables Dim Distance.
Distance – Specifies a distance after which the reflection rays will not be traced. Dim Falloff – Sets a fall off radius for the dim distance. Example: The Reflection Color Parameter This example demonstrates how the Reflection color parameter controls the reflectivity of the material. Note that this color also acts as a filter for the diffuse color (e.g. Stronger reflections dim the diffuse component). Refraction Refraction – Enables Refraction of the material. Refraction Color – Specifies the refraction color.
Note that the actual refraction color depends on the reflection color as well. See the Energy preservation parameter below.
For more information about refraction color, please see the below. Fog color – Specifies the attenuation of light as it passes through the material. This option allows to simulate the fact that thick objects look less transparent than thin objects. Note that the effect of the fog color depends on the absolute size of the objects and is therefore scene-dependent unless the Fog system units scaling is enabled.
The fog color also determines the look of the object when using translucency. For more information, please see the and examples below. Fog Multiplier – Smaller values reduce the effect of the fog, making the material more transparent. Larger values increase the fog effect, making the material more opaque. Fog Bias – Changes the way the fog color is applied. Negative values make the thin parts of the objects more transparent and the thicker parts more opaque and vice-versa (positive numbers make thinner parts more opaque and thicker parts more transparent). IOR – Specifies the index of refraction for the material, which describes the way light bends when crossing the material surface.
A value of 1.0 means the light will not change direction. For more information, please see the below. Refraction Glossiness – Specifies the sharpness of refractions. A value of 1.0 produces perfect glass-like refraction; lower values produce blurry or glossy refractions. Use the Subdivs parameter below to control the quality of glossy refractions.
For more information, please see the below. Affect shadows – When enabled, the material will cast transparent shadows, depending on the refraction color and the fog color. This only works with V-Ray shadows and lights. Max depth – Specifies the number of times a ray can be refracted. Scenes with lots of refractive and reflective surfaces may require higher values to look right. Affect channels – Specifies which channels will be affected by the transparency of the material.
Color Only – The transparency of the material will affect only the RGB channel of the final render. Color+alpha – Causes the material to transmit the alpha of the refracted objects instead of displaying an opaque alpha. Note that currently this works only with clear (non-glossy) refractions.
All channels – The transparency of the material will affect all channels and render elements. Dispersion Dispersion – When enabled, true light wavelength dispersion will be calculated. For more information, please see the below. Abbe – Increases or decreases the dispersion effect. Lowering it widens the dispersion and vice versa. Translucency Translucency – Enables Refraction translucency.
Type – Selects the algorithm for calculating translucency (also called sub-surface scattering). Note that Refraction must be enabled for this effect to be visible. Hard (wax) model – This model is specifically suitable for hard materials like marble. Color+alpha– This is the most realistic SSS model and is suitable for simulating skin, milk, fruit juice and other translucent materials.
Back-side Color – This parameter allows you to additionally tint the SSS effect. Scatter Coeff – The amount of scattering inside the object. 0.0 means rays will be scattered in all directions; 1.0 means a ray cannot change its direction inside the sub-surface volume. Fwd/back Coeff – Controls the direction of scattering for a ray. 0.0 means a ray can only go forward (away from the surface, inside the object); 0.5 means that a ray has an equal chance of going forward or backward; 1.0 means a ray will be scattered backward (towards the surface, to the outside of the object). Thickness – Limits the rays that will be traced below the surface.
This is useful if you do not want or don't need to trace the whole sub-surface volume. Light Multiplier – Multiplies the translucent effect. Example: The Refraction Color Parameter This example demonstrates the effect of the Refraction color parameter to produce glass materials. For the images in this example, the material has a gray Diffuse color, white Reflection color, and the Fresnel option is turned on.
V-Ray 3 for SketchUp features interactive rendering technology that allows users to see results immediately upon changes to the model. In this course, Brian Bradley both introduces and helps to solidly ground you in your ability to use the tools and features found in the powerful V-Ray for SketchUp rendering solution. After he familiarizes you with the V-Ray interface, Brian demonstrates how to add illumination to your scenes using the program's versatile lighting tools.
He shows how to work with different light types for adding both artificial light and natural-looking daylight. In addition, he covers the V-Ray camera, materials, map types, render elements, FX tools, and more.
Instructor. Brian Bradley is a self-taught 3D artist and business owner.
Brian started experimenting with creative software and 3D applications around the end of 1993, wondering whether or not he could make a living working with such cool tools! By 1998 he had started his own multimedia business, working on projects ranging from flying logos to graphic design for clothing and vehicles to entire product and architectural visualization projects. While learning the tools of his trade, Brian developed a keen awareness of the need for well-explained, high-quality training that could make software tools accessible and open to anyone who wanted to learn them. In 2007 he turned the attention of his family business toward the full-time teaching of the graphic design and production tools he loves to others. Related courses.

My name is Brian Bradley, and I am really looking forward in this course to taking a look at how we can make use of the extremely powerful V-Ray 3 render engine as a lighting and rendering solution in SketchUp. As the course has partly been designed to help newer users get up and running with V-Ray, we will take a look in Chapter One at how and where we can find V-Ray tools and controls inside the SketchUp user interface, as well as having a good look at the controls found on the V-Ray frame buffer window, as well. We can then move on to V-Ray's extremely powerful and versatile lighting tools, learning essentially how to add illumination to our scenes. This will include an examination of the V-Ray sun and sky options that can be used to add natural looking daylight to our renders, as well as at the V-Ray light types that can be used to mimic more artificial looking, or manmade light sources.
Global illumination is, of course, an extremely important aspect of. Practice while you learn with exercise files. Watch this course anytime, anywhere. Course Contents. Introduction Introduction.
