This depends on your renderer. You are talking about the model made by others. Generally, the rendering parameters have been set, so you don't need to adjust them. If it is the default scanline renderer commonly used in Game model, you only need to turn up the anti-aliasing parameter in the advanced option in the rendering settings, use Catmull-Rom as the filter, and turn on global supersampling, and the rendered effect will be very fine.
2. how to set the preferences to make the model display the best?
The display driver is related to the model display in the preferences, and the selection driver and configuration driver are available in the custom menu-viewport tab. Depending on your system and graphics card, systems above vista can support dx1.xp and only dx9. This is generally optional when you start max for the first time. After using dx, turn on all anti-aliasing, adjust the parameters of background texture to the highest level, and the following display is adjusted to linear filtering mode.
3. Turn on the display mapping effect in the material editor. You can choose blue or red as the button of that box, and red is the hardware rendering of the graphics card, which is relatively slow.
4. Press 8 to open the environment editor, and you can adjust a comfortable background map or color. alt+B can display the background map in the viewport.
these are the places that basically affect the display effect.
