1.Maximum number of model faces: To improve product performance, it is recommended to remove unnecessary structures. Please try to control the total number of surface of the model to 500,000 triangle (250,000 quadrilateral surface), not more than 5,000,000 triangle (2.5 million quadrilateral surface). If it is exceeded, the model will not be uploaded.
2.The front side of the model should correspond to the front view of 3D max. If not, please adjust your model.
3.The model must not have lost texture phenomenon. (Using shortcut shift+T to quickly view the texture. Please reassign the texture path if it is missing, or delete the unwanted texture path.)
4.Turn on Gamma/LUT correction. The value is 2.2. (Improve image contrast effect, rendering more realistic)
5.Do not keep non-model components in Max model files, and do not keep unwanted scenes. Or the designer will have a position shift when rendering. (e.g: cameras, non-illuminated lights, etc.)
6.The model size should be modeled according to the real product size. And the model should not be larger than 10 meters. (The length, width and height of the model must not exceed 10m)
