To achieve the effect of stage lighting, just import the required optical network files.

How to use 3Dmax optical network files;

1, create photometric lights in the scene: create >；; & gt light & gt photometry & gt& gt target point

Adjust the view as shown in the figure below (not necessarily the same, just easy to observe);

2. Confirm that the target point is selected, and then click Modify to open the Density/Color/Distribution rollout.

Select "Web" in the "Distribution" drop-down menu, expand the "Web Parameters" rollout, and then click the button next to WebFile;

3. From the pop-up click, select an optical network file to open;
