How does 3DMax make depth of field effect with the target camera? How to make depth of field effect with 3DMax target camera

3dsMax is a professional 3D modeling, rendering and animation software, which can be used to create a wide world and high-quality design. Such a powerful modeling tool can inject vitality into the environment and landscape. 3dmax uses intuitive texturing and coloring tools to create detailed designs and props. You can also make professional renderings iteratively to complete artistic control. Self-study 3DMAX must choose a systematic tutorial course, which provides basic, advanced and advanced courses. The case is novel and the technology is excellent. You must see it.

How to make depth of field effect with 3DMax target camera

When we opened the scene file, we saw that two piles of apples had been created in the scene. At this time, you need to render a very beautiful depth of field effect.

First, we need to know something about cameras. In the previous panel creation, we learned geometry, graphics and lighting. The fourth item in the panel creation is the camera. Click on the camera, there are two options: standard camera and VRay camera. Standard cameras include two kinds of cameras: target cameras and free cameras. VRay includes VR spherical camera and VR entity camera, and there are four kinds of cameras. Then commonly used cameras are target cameras and VR entity cameras.

In this case, we need to create a target camera and create it in the scene in the same way as creating lights. Because we need to make the depth of field effect, the position of the camera target point is very important. Finally, we must put the position of the camera's target point on the object, so that when rendering, the position of the target point, that is, the clearest position in the image, deviates from the position of the target point, and its depth of field effect is stronger, that is, more blurred. According to this principle, it will produce a very real front and back depth of field effect.

At the same time, we need to set the camera angle. Let's take a look at its position in the four views. Click Modify to set its lens to 43.456, field of view to 45, and target distance to 12.298.

Next, we need to set the renderer, because when rendering the depth of field, we must set the relevant depth of field parameters under the renderer, so we need to click to open the renderer setting parameters panel. Set the renderer to VR renderer, click the VR basic item, open the parameters of VR camera, and check on under the depth of field. After checking, the depth of field effect will appear in the image when rendering, and its aperture value will be set to 0.6 and focal length will be set to 200. After checking, the depth of field effect will be obtained according to the camera we created in the scene and the position of the target point when rendering. Of course, through this place to set, we see that there is motion blur below. When motion blur is checked, the effect of motion blur will appear. We can continue to cancel.

After setting the renderer, if we render directly at this time, we will see a very incorrect effect because we must switch to the camera angle. Here we can directly press the shortcut key C to switch to the current camera angle. Press Shift +F to enable the security box. We can see that the boundary between the top and bottom of the whole scene has changed. In other words, after pressing Shift +F, the security box is displayed, and the effect we see is the normal size of the final rendering. The state of not opening the Shift +F security box is just an effect we watch in 3dmax, so we should try to open Shift +F before rendering.

At the same time, we can press the p key to switch back. If we need to create a camera quickly, we used to create a camera just like creating a light. At this time, we don't have to click any button, but we need to create such an angle. It is very convenient to create it in perspective view now. Just press Ctrl +C, and then we can see that the upper left corner automatically becomes camera 002. Press the P key at this time, and you will see that the viewing angle is automatically set to the camera. This is a quick way to create a target camera.

Of course, we delete it, press the C key again to switch back, and click Render to see the rendering effect of the depth of field at this time.

The above is "How to make depth of field effect with 3DMax target camera". You will know how to operate after reading this tutorial. There is no skill in learning 3dmax, and you can master it naturally with more practice. Click this link to learn more about the 3dmax tutorial:
