Coronashadows

Hello, how to solve this issue?

set type of shadows in all maxlights in the scene to CoronaShadows

where can i change these settings?

Please, learn the 3DsMax basics, and then try Corona, Vray, whatever…!!!
Go for Corona without the 3DsMax basics, it’s like to try to ride a car without steering wheel…!!!

You can always…

Anyway, select the ligth and in the properties tab under “general parameters” pick “corona shadows”
