IES (Lighting Engineering Society) lighting file is a file format, which can be used to simulate the light emitted by different types of lamps and control the intensity and direction of light. IES illumination file is an important tool to realize real lighting effects, and 3DMax is a widely used 3D modeling software. By importing IES files into 3DMax, various lighting effects can be simulated more realistically. This article will introduce how to import IES lighting files in 3DMax. Operation method of 3dmax importing ies lighting: 1. Click Lighting in the Create panel. 2. Switch "Standard" or other to "Photometric Lighting" 3: Create photometric lighting, and generally select "Target Lighting" 4. Adjust the position of the lamp (later) 5. Aim the light source at the center 6. Find the light distribution type in the right panel 7: change the type from "Uniform Sphere" to "Photometric Distribution". Click the bar chart below the spherical grid distribution and select an ies file. 8. Then continue to adjust other parameters. Through the introduction of this article, readers have learned how to import IES lighting files in 3dsMax to achieve a more realistic lighting effects. Readers can follow the steps described in this article to achieve more realistic and realistic lighting effects. I hope these operating methods can help you to create more realistic works when you need to use this software for modeling and rendering.
