3D max20 12 was rendered repeatedly after vray rendering.

In fact, you checked Show calc.phaseh, and it is not recommended to check these two items when rendering at last, which will increase memory consumption. In addition, the rendering you mentioned several times is related to the minimum and maximum sampling of Min rate and Max rate.

For example, when you set the minimum sample to 0 and the maximum sample to -4, the system will calculate it five times. When the minimum sampling is 0, the system will calculate the samples at-1, -2, -3 and -4 in turn. Of course, the more sampling processes, the better the effect.

3ds Max20 12 is divided into 12 chapters from introduction to proficiency, including how to use 3ds Max for primary modeling and advanced modeling, how to use materials and maps to make effects, how to make basic animations, how to make renderings and architectural animations, etc.

This paper introduces scene objects, object transformation, file and scene management, creation and modification of synthetic objects, cameras and lighting, environment and effects.
