How to Draw a Plane Verticaly in 3ds Maxc
The Plane, Disc, and Sphere are each a type of VRayLight with similar options.
Overview
Plane, Disc, and Sphere lights are types of VRayLight objects. These are expert general-purpose Five-Ray lights for lighting scenes to simulate real-globe low-cal sources like lamps and ceiling lights.

Sample Uses
By default, Five-Ray renders the light source if it is seen in the camera, every bit shown in the examples beneath. To render without seeing the light source, enable the low-cal'south lnvisible option.
Annotation: When aPlane,Disc, orSphere light is visible in the rendering, aliasing at the edges of the light source tin occur. Lens Effects such equally the Blossom Result (as used in the example images below) and Glare Effect are one way to hide the aliasing, while some other is the utilise of a VRaySoftBox map.For data on the cause of the aliasing and solutions for it, come across Notes beneath.

Parameters - General Rollout
On – Turns the VRayLight on and off.
Blazon – Specifies the shape and function of the light:
Plane – The VRayLight takes the shape of a planar rectangle.
Sphere – The VRayLight has the shape of a sphere.
Dome – The VRayLight emanates from a spherical or hemispherical dome around the scene extents. See the Dome Light page.
Mesh – Allows the usage of any mesh object as the shape of the light. Meet the Mesh Light folio.
Disc – The VRayLight takes the shape of a planar disc.
Targeted– When enabled, a split up target object is attached to the calorie-free source. This target object can be moved separately from the calorie-free source, making information technology easier to betoken the light within the scene. The value specifies the distance from the calorie-free source to the target. While any type of VRayLight can have a target, the target is truly useful only withAirplane andDisc lights. This selection can exist changed only in the Modify tab.
Length – The length of aPlane light source, measured in scene units.
Width – The width of thePlane light source, measured in scene units.
Using the length, width or 5 size parameters is the recommended method for controlling the light's size. Avoid scaling the calorie-free. Uniform scaling can be used when the scene needs to be scaled upward or down, but non-compatible scaling produces skewed or elliptical shapes, which may produce incorrect results.
Radius – The radius of theSphere orDisc low-cal source, measured in scene units.
Note: The size of the light source sometimes affects the low-cal's intensity, shadows, and low-cal diffusion depending on what is selected for theUnits parameter.For more information, see Case: Light Units, Light Size and Shadow Crispness.
Units – Specifies the low-cal units. Using right units is essential when y'all work with the VRayPhysicalCamera. The calorie-free automatically takes the scene'due south unit scale into consideration to produce the correct result for the calibration you are working with. The possible values are:
Default (image) – The colour and multiplier directly determine the visible color of the light without whatsoever conversion. The low-cal surface appears with the given color in the last epitome when seen straight past the camera (assuming there is no colour mapping involved).
Luminous ability (lm) – Total emitted visible light power measured in lumens. When this setting is used, the intensity of the light does not depend on its size. A typical 100W incandescent light bulb emits about 1500 lms of light.
Luminance (lm/grand²/sr) – Visible low-cal surface power measured in lumens per square meter per steradian. When this setting is used, the intensity of the calorie-free depends on its size.
Radiant power (Due west) – Total emitted visible light ability measured in watts. When using this setting, the intensity of the light does not depend on its size. Keep in mind that this is not the same equally the electric power consumed by a lite seedling for example. A typical 100W light bulb simply emits between 2 and 3 watts as visible lite.
Radiance (W/thou²/sr) – Visible calorie-free surface power measured in watts per foursquare meter per steradian. When this setting is used, the intensity of the calorie-free depends on its size.
Multiplier – Multiplier for the light color, and likewise the light intensity for some Units settings.
Manner – Specifies the mode in which the color of the calorie-free is determined:
Color – ТheColor swatch specifies the color of the calorie-free rays and of the light source itself when visible in renderings. ForUnits settings other thanDefault (image), this colour is normalized then that merely the color hue is used.
Temperature – Тhe color of both light rays and the light source itself is specified past theTemperaturevalue expressed in Kelvin.
Map – Enables the use of a texture for the light surface when aAeroplane orDisc lite type is used. The push under this option selects the map to use. The texture intensity is also affected by theMultiplier value. The calorie-free uses the texture's blastoff as opacity map.
Example: Light Source Size and Shadow Crispness
The following images show how the size of a Sphere lite source affects shadows. Larger low-cal sources produce blurrier shadows, while smaller light sources produce sharper shadows:
Radius = 0.five ; Units set to Luminous power (lm)
Radius = 1.0 ; Units set to Luminous ability (lm)
Radius = 2.0 ; Units set to Luminous power (lm)
Example: Lite Size and Intensity
In the previous case, the calorie-free emitted past the light in all images is of the same intensity regardless of the calorie-free source's size. This is because the light's Units were gear up toLuminous ability (lm), which doesn't depend on the light source size for intensity. Both theLuminous power (lm) and Radiant power (Westward) settings allow the light source to retain the same intensity regardless of the low-cal source'southward size.
The same is not truthful for other Units settings. With theDefault (image), Luminance (lm/m²/sr) andRadiance (W/m²/sr) settings, the light's intensity is directly affected by the size of the light source.
Radius = 0.5 ; Units = Default (prototype)
Radius = 1.0 ; Units = Default (image)
Radius = ii.0 ; Units = Default (paradigm)
Parameters - Rectangle/Disc Light Rollout
This rollout is merely bachelor when theBlazonis set toPlane orDisc.
Directional – By default, the calorie-free from the Plane or Disc light is spread out equally in all directions on the side in which the lite points. Equally this parameter is increased toward a value of 1.0, the spread narrows, making the light more directional. A value of 0 (default) makes the calorie-free smoothen in all directions around the light source. A value of 0.5 pushes the light cone to a 45-caste angle, and a value of i.0 (maximum) makes a 90-caste calorie-free cone.For more information, run across the Directional Spread example below.
Preview – Allows the light'south spread bending to be seen equally a wireframe in the viewport, as information technology is fix by the light's Directional parameter.
Always – The preview is always displayed.
Selected – The preview is displayed only when the light is selected.
Never – The preview is never displayed.
Preview texmap – If a texture is used to bulldoze the light, enabling this shows the texture in the viewport. This option is grayed out if your 3ds Max viewport is configured to use Nitrous viewport commuter. To enable, switch to the direct3D viewport.
Example: Directional Spread
The Directional parameter controls the spread of the Plane or Disc light. A value of 0 produces the maximum spread of low-cal in all directions as seen in effigy ane, while a value of 1 creates a narrow lite beam every bit seen in figure iii.
Plane light with Directional = 0, 0.five, i.0
Preview = Ever
The following example shows the result of the Directional parameter. Note that the plane calorie-free itself appears to turn black as the value gets closer to 1.0. This is due to the simplified directional distribution. The calorie-free is forced only in the forrard direction, so the aeroplane appears dark when viewing it from the side. This miracle does non occur with existent-world lights because they showroom more complex directional distribution.
Directional = 0.0
Directional = 0.6
Directional = 0.8
Directional = 1.0
Parameters - Options Rollout
Exclude – Opens the 3ds Max Exclude/Include window for selection of objects to exist excluded or included in illumination and/or shadow-casting for this calorie-free.
Cast shadows – When enabled (the default), the light casts shadows. Plough this option off to disable shadow casting for the light.
Double-sided – When the light is a Plane or Disc type, this option controls whether light is beamed from both sides of the light icon. This field has no effect for Sphere type of light source. For more data, run across The Single-Sided vs Double-Sided Lights instance beneath.
Invisible – Controls whether the shape of the light source is visible in the rendered paradigm. When this selection is disabled, the lite source is rendered in the color specified past theColour orTemperature setting in the Intensity rollout. This option only affects the visibility of the calorie-free when seen directly by the camera or through refractions. The visibility of the light with respect to reflections is controlled by theBear on reflections choice.
Note: Regardless of whether this selection is enabled, the light source is still taken into account past Global Illumination calculations, which might cause secondary GI rays to be blocked by or bounced off the calorie-free's surface. To make the low-cal completely invisible to GI, place a VRayColor texture map into the light'southward texture slot and fix thealpha value for the VRayColor map to 0.0.
Occlude other lights – Controls the beliefs of invisible lights in relation to other light sources. When enabled, the light blocks the lighting from other lights as if information technology's visible. Likewise in reflections the lite behaves every bit it'south visible and occludes other lights. When disabled, the lite is transparent for other lights and does not occlude them. This option doesn't affect visible lights (as they always occlude other lights) and dome lights (which are always condiment).
Touch on diffuse – Determines whether the light affects the diffuse portion of the materials. Thevalue controls the low-cal's contribution to the diffuse portion of the materials.
Bear on specular – Determines whether the light affects the specular portion of the materials. The value controls the low-cal's contribution to specular reflections.
Affect reflections – Specifies whether the light source appears in reflections.
Affect atmospherics - Specifies whether the light influences the atmospheric effects in the scene. The value determines the amount of interest.
Instance: Single-Sided vs Double-Sided Lights
This example demonstrates how aAirplane calorie-free is afflicted when theDouble-sided option on the Options rollout is enabled or disabled. The light is pointed away from the hallway.

Parameters - Sampling Rollout
Shadow bias – This value moves the shadow toward or abroad from the shadow-casting object (or objects). College values motion the shadow toward the object(s), while lower values move information technology away. If this value is likewise extreme, shadows can "leak" through places they shouldn't or "detach" from an object. Other effects from extreme values include Moire patterns, out-of-place night areas on surfaces, and shadows not appearing at all in the rendering.
Cutoff – Specifies a threshold for the light'southward intensity, cutting off the low-cal's event on a surface when it falls below this value. Lights lose intensity due to GI bouncing or decay. When light hits a surface but its intensity falls below the cutoff, the effect of the calorie-free on that surface is not computed. This can exist useful in scenes with many lights, where y'all want to limit the outcome of the lights to some distance around them or reduce computations (and thus reduce rendering time) where the low-cal's bear on is negligible. Larger values limit the light'due south effect on objects to a smaller area around the light source, while lower values increment the range of the light's upshot. If you specify 0.0, there is no cutoff and the light is calculated for all surfaces regardless of intensity loss. The default value is 0.001.This parameter is not available when the renderer is set to GPU.
Tex resolution – Specifies the resolution at which the texture is resampled for importance sampling.
Parameters - Viewport Rollout
Enable viewport shading – When enabled, the effect of the calorie-free is visible in the viewport.
Viewport wire color – When enabled, the light'south wireframe is displayed in the specified color in viewports.
Icon text – Enables or disables the preview of the light name in the viewport.
Notes
-
When using texture-mapped Plane lights, information technology is best to have GI enabled. This allows V-Ray to apply combined direct and indirect sampling for the lite, which greatly reduces the racket for surfaces close to the light.
- The effect of all textured V-Ray lights can be shown through the Nitrous preview in the viewport.
- When an Area light is visible in a rendering, the edges of the lite source can appear to exist aliased. This happens considering the light source color is ordinarily very, very bright, far across the range of what an ordinary monitor can display, and antialiasing involves changing the colors of pixels at the edges of objects to a colour midway between two other colors. When V-Ray applies antialiasing to a lite source's edges, whatsoever colors midway between the light color and surrounding object colors are yet very bright, beyond what a monitor can display, and the pixels that are supposed to provide a smoothen transition from the light source to the surrounding objects announced to be the same color as the low-cal source. As a result, there appears to be no antialiasing at all around the light source. To solve this problem, use a VRaySoftbox texture on the light source to cause its brightness to reduce at the edges, or use Lens Furnishings to soften and mistiness the aliased edges of the lights after rendering.
