In the eighth week of work, my main task is Unwarping and Texturing in Rizom UV and Substance painter. Before Unwarping for car, the most important process was to divide shaders.
Car
As shown in the picture, I divided the car into 8 parts, namely 8 UVs.
After Unwarping is over, it is the Texturing phase. As shown in the picture is my production process in substance painter. The rendering effect of Vray is as follows:
Finally rendering in MAYA，testing maps .

Unwarping in RizomUV
Make lighting UV in MAYA
Since my game project requires lighting and baking, lightingUV is essential. Although the second set of UVs is automatically generated when the model is imported into Unreal, such UVs are sometimes not easy to use.
You can copy a new UV at the position shown in the figure, and scale the UV slightly to make the two UVs slightly different.
Texturing in substance painter
Since the model is low poly, we need to get high poly Normal and AO in Zbrush. If this is not the case, the visual effect of high polygon will not be obtained.
However, due to the modification of the model, the problem as shown in the figure will be encountered.
