How to test vignetting with VRay camera? Testing the process of vignetting with VRay physical camera

Vray renderer has ray tracing and global illumination, which can replace Max's original linear scanning renderer. Mainly used in interior, architecture, landscape design and other industries, and can be matched with 3dsMax, Maya, Sketchup, Rhino, Revit and other software. If you are inefficient, stagnant or don't know where to start when learning VRay by yourself, and you are worried about detours and wasting time, then you must take a look at "3dmax2020 Rendering Map VRay Rendering PS Later Panorama Course", which will help you solve all these problems!

Testing the process of vignetting with VRay physical camera

We take a photo with a film camera, and there is a black blank holder effect around the photo, which can also be rendered in 3dmax or processed in Photoshop after rendering.

Open the scene file, then we need to create a camera for the scene, select a camera, switch to VR, select a VR entity camera, drag and drop it in the scene to create it, and we can set its specific location.

When entering the modification panel, we need to change its settings, such as setting its film gate size to 36, focal length to 40, and zoom factor to 1.0. In order to make the scene brighter, we should set its aperture coefficient to 1.6, that is to say, we can set the brightness or exposure of the final rendered picture in the camera parameters by using the VR entity camera. The VR physical camera is more adjustable.

In the parameters, we can see the option of "vignetting". By default, vignetting is selected and the value is 1. At this time, we press the C key to switch to the angle of the VR physical camera. Click Render to see the rendering effect when the vignetting value is 1.

We saw that it was a little dark around the picture, but it was not particularly serious. Let's set its value to 2 and see the rendering effect again. At this time, there is an obvious blank holder effect.

Let's continue to set the vignetting value to 4 and see the rendering effect at this time. Obviously, the larger the halo value, the darker the surrounding picture.
