The movie Doraemon: Nobita's New Dinosaur, the 40th memorable work in the film series, tells the touching story of Nobita's encounter with the twin dinosaur queue and emus.

The following small editor will give you a brief introduction to how morie uses maya to represent dinosaurs as vivid as illustrations in the atlas. As a veteran rendering farm, Blue Ocean Creative Cloud also perfectly supports maya rendering at the beginning of its establishment, and integrates aspera and lhdt high-speed transmission engines, users can drag and drop to submit jobs on the client side, and the rendering results are automatically transmitted back, convenient and fast!
Morie, who works as a cg animation supervisor in Doraemon: Nobita's New Dinosaurs, said in an interview: "Using 3D cg to represent dinosaurs like illustrations in a picture book, rather than physical photos, is a new challenge for the company. ”
The two new dinosaurs (image 1) and some dinosaurs (the first 2 in image 2) that appear mainly in the film are represented in the painting. In addition, 25 dinosaurs such as TitanOsaurus (image 2 deep) and Yanglong (image 3) were all represented using maya's 3dcg.

Mori Jiang said that the texture of dinosaurs, although it is an animation style, has taken a lot of effort to balance the sense of reality. As the animation does not deform too much, note slightly closer to reality. Of the 25 dinosaurs that appear in the movie, 4 are known as feathered dinosaurs. The feathers here are not depicted as textures, but are set to actually generate 3d hairs. In order to show a proper sense of realism, xgen was flexibly used behind the scenes.

xgen is used for the body hair of velociraptors
Xgen works in two ways, one is "delete" and the other is "interactive grouping".
In the interactive grouping, it is easy to create the flow of hair, and there are advantages such as making the hair flutter through simulation. But this time no simulation was used, and because "custom shader parameters" were required, burn was chosen.
The delete function is simply defined as one. (It is said that there is also a method of using multiple marks according to the type and part of the hair) And in order to exaggerate, thicker hairs are deliberately set.

As a workflow, we first set masks where hair is not needed. The paint function on maya and the editing combination of the ptex (Texture Mapping Technique) file are used to set the mask. Slightly more complex parts such as armpit and joint parts, roughly draw out the area with the Maya Paint Tool, write on the texture, modify, and then read as ptex.

Initially specifying black and adding white where hair is needed makes setting easier.
Then, using the grooming tool, the length, flow direction, angle of the hair ends, etc. were slightly adjusted. However, due to the fact that the model data contains triangle polygons, the clutter of hairs can be conspicuous when moving through the animation. Therefore, the model data composed only of quadrilateral polygons composed of xgen for signature was prepared, and the correspondence was retrieved and copied from the original model. In the setting of rooming, Mao's impression will change greatly. In order to show a fierce, rough image, Villaput added some noise, and in order to show the hairband, the hair was adjusted very coarsely.
