C4D modeling, mostly processed by four-sided wiring, the body is not collapsed, the number of faces is small, the operation does not take up too much resources, and it is convenient to do animation. Use OCtane to render the direct output, open the file and directly render the image as shown, but the light of each image is adjusted. In addition, the FBX format is exported, which is convenient for max users. However, in order to avoid the collapse of the broken surface, I have basically no problem in max2018. The material lighting needs to be adjusted by myself~~The obj and fbx formats only have models, colors and textures that need to be added in the corresponding software.
