V-Ray smoothly integrates itself into 3ds Max and artist's or designer's workflow. V-Ray is the industry standard for render quality, speed, reliability, and ease of use. The rich and broad features of the Vray plugin for 3ds Max create a versatile experience to adapt to all major industries or independent projects.

Professionals frequently choose this software to create unique IES light patterns that differ from the commonly seen/used by most artists/visualisers.Please note that, in real projects, users are strongly advised to ask for permission from the designated lighting designer before using this artistic approach!The “Creator IES” dialog provides users with the unsurpassed ability to create IES web files “from scratch”, or by simply editing a loaded one.Its dialog box consists of two representations of the light pattern:Curve editor graph, and picture thumbnail. The Curve editor depicts a graph of the IES light pattern (i.e. The entire length of the curve represents different parts of the light pattern, which can be easily edited by simply clicking and dragging (upwards or downwards) on any part of the curve.The adjacent picture thumbnail depicts the resulting image from the curve editor shape, in real time.The “before and after” images below highlight how the “Creator IES” software can easily and intuitively create an IES web file “from scratch”.
Hi Boris,Thank you very much for participating here!!!!With regards to your query, I am going to look into this, and follow up on your alleged problems.By the way, what did you mean by symmetrical light?Regardless of the rendering engine being used, the 'PhotometricLight' light type works for both mental ray and VRay, and believe users can resize the light source from its physical parameters!So, if you're using 'VRayIES' light object/s and need to increase its scale, you should perhaps consider changing it/them to 'PhotometricLight' type.As mentioned earlier, I will look into this!Ta.
Photometric lights utilize an.ies file which contains the distribution profile for the light. An.ies file contains complete specifications of a real world light bulb or tube including the shape of the light's cone and the steepness of the light's falloff. Visualizing IES ProfilesThe properties of an IES file can be visualized with Photometric Viewer software, which you can easily find online. Visually, the IES profile uses a graphed curve to show the shape and intensity of the light's emission. Depending on the software used, you might also be able to render a grayscale representation of how the light will look in a scene. Using a Photometric Viewer will help you better understand how the IES files you are using will affect your scene's lighting.The graph below shows the IES profile of a typical bollard or post light, a type of light commonly used in architectural outdoor scenes. The rendered thumbnail is shown as an inset.Parametersenabled – Turns the VRayIES light on and off.enable viewport shading – When enabled, the effect of the VRayIES light will be visible in the viewport.show distribution – Shows the IES profile distribution as a mesh around the light source in the viewports.targeted – Makes the VRayIES targeted.ies file (button) – Specifies the.ies file that defines the light distribution.rotation X/Y/Z – Rotates the light shape in relation to the target.cutoff – Specifies a threshold for the light intensity, below which the light will not be computed.
This can be useful in scenes with many lights, where you want to limit the effect of the lights to some distance around them. Larger values cut away more from the light; lower values make the light range larger. If you specify 0.0, the light will be calculated for all surfaces.shadow bias –Moves the shadow toward or away from the shadow-casting object (or objects). If the Bias value is too low, shadows can 'leak' through places they shouldn't, produce moire patterns, or make out-of-place dark areas on meshes. If Bias is too high, shadows can 'detach' from an object. If the Bias value is too extreme in either direction, shadows might not be rendered at all.cast shadows – When enabled (the default), the light casts shadows. ellipse (width).
ellipsoid (length). ellipsoid (width)height – Specifies the height for applicable light shape types.width – Specifies the width for applicable light shape types.length – Specifies the length for applicable light shape types.diameter – Specifies the diameter for applicable light shape types.shape subdivs – Most users will not need local control of subdivs, however this parameter controls the number of samples V-Ray takes to compute lighting locally for this light. Lower values create more noise, but render faster. Higher values produce smoother results but take more time to render.To activate this parameter and specify a value, use the Use local subdivs parameter under the V-Ray tab in the Render Setup window. Note that the actual number of samples also depends on the. By default, this parameter is controlled by the Min shading rate parameter in the Advanced/Expert user modes of the Image sampler (Antialiasing) rollout.color mode – Specifies the mode in which the color of the light will be determined:color – The light color is directly specified by the Color parameter. Temperature – The light color temperature (in Kelvin) is specified by the Temperature parameter.color – Specifies the color of the light.color temperature – Specifies the light color temperature in Kelvin.intensity type – Specifies the units for light strength:power (lm) – Sets the units of power in lumens.
Intensity (cd) – Sets the units of intensity in candelaintensity value – Specifies the strength of the light.area speculars – When disabled, the particular light will be rendered as a point light in the specular reflectionsviewport wire color – Changes the wireframe color of the light in the viewport. This is useful to visually recognize groups of lights from one another.icon text – Turns the viewport icon text on or off.Exclude – Brings up the 3ds Max include/exclude button which allows the user to exclude objects from illumination and shadow casting.
