There is a need for stylized rendering on UE4 recently, so take the opportunity to write about the relevant production tutorials. Corresponding to the Japanese style rendering technique, the key or normal processing. Normal processing before the translation of a lot of data, so also do not explain, such as the latest UE4 on the card relief game "four goddess Ol" UE4 The development of the four goddess example detailed here. Http://cgworld.jp/feature/201611-ue4fst2016-4gdss.html with Max script or Python, it's easy to implement normal replacement and baking tools on 3dsMax or Maya. The time relationship here, or temporarily use the Softimage xsi plugin usernormaltranslator used in GGXRD. Usernormaltranslator installed and set up YouTube usernormaltranslator tutorial videos, but also for those who are not good at Japanese or English to understand the convenience, here also simple to do a Chinese description. The first is to download the GithhubUsernormaltranslator plug-in. Https://github.com/Gotetz/UserNormalTranslator, then start xsi, drag the Usernormaltranslator.xsiaddon into the window, even if the installation is successful.because XSi and 3ds Max interact with different modes of keying:The S key toggles the switch between the selection mode and the viewport operation mode, and then you can do the viewport action with the left and right mouse button a key is selected to fit the viewport x C s key correspondingZoom, Rotation andMoving Therefore, it is recommended to set the interactive mode to 3ds Max or Maya mode at startup to select Display normals in the XSI setting viewport, and in 2014, it has also encountered problems that the normals cannot display because of the FBX object scaling problem. This can be removed from the normal rotation function of the xsi when imported xsi can set the normal value usernormaltranslator use the Add function of the Usernormaltranslator panel normal, the example in the video is when the light from the top down, The character's face turns black, and by adding an upward vector through the normals, the light can be well matched. Normal multiplication can increase the methodthe weight of the line to a certain direction. One of the main functions of the usernormaltranslator is the normal spheroid, which is helpful for making stylized rendering such as canopy. For example, in the art just finished part of the leaves, the normal is taken from each leaf polygon, coloring seems to be more cluttered. Open Normals in xsi display simple mate normals multiply the light and shade distribution can be more hemispherical through the Create Center, you can change the globe position to move the sphere down to reduce the shadow portion
Normal smoothing, this is a lot of tools. Copy of normal to vertex color, convenient for editing, some requirements also need the model has 2 sets of normals to cope with different coloringwhat Usernormaltranslator lacks.1 Normal copy function, according to the distance relationship between the vertex copy normal information from the source model to the target model, this in the clothing and hair normal adjustment to help 2 xsi in the country is not mainstream, there is time or through his JS source, ported to 3dsMax or Maya better. The next lecture is about how to implement UE4 support for stylized rendering
UE4 implementation of stylized rendering (i): Use of usernormaltranslator tools
