What is IES light VRay?

Overview. Photometric lights utilize an . ies file which contains the distribution profile for the light. 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.

What is VRAY ambient light?

The V-Ray Ambient Light is a V-Ray specific light source that can be used to create light that doesn’t come from a specific direction. It can be used to simulate GI, ambient occlusion, etc. UI Path: ||obj Network|| > V-Ray > Light > V-Ray Ambient Light.

IES (Illumination Engineering Society) is a standard digital file in ASCII format, which measures the distribution of light, in other words the intensity of the light and its shape.

How are IES lights used in 3ds Max?

By loading an .ies file, the light’s properties are recreated within 3ds Max and used by V-Ray during rendering. IES lights are particularly useful for architectural interior renderings, where it can be important to show the actual result of using specific man-made light sources in the scene.

How to create a vrayies object in 3ds Max?

How does vraylightmtl work in 3ds Max chaos?

VRayLightMtl supports color opacity. This means that it uses the “color” output of textures rather than their “mono” output, in difference from the Opacity slot of VRayMtl materials. Emit light on back side – When enabled, the object emits light from its back side as well. When disabled, the material is rendered as black on the back sides.

How does IES profile work on 3ds Max chaos?
