D5 lighting limits

i encountered a problem
a message appeared that lighting should not exceed 4096

Hi there,

I apologize for the inconvenience. Can you perhaps send us a screenshot of the error prompt? Currently, the maximum number of artificial and spontaneous lights in a viewport is 4096. If this limit is exceeded, it is recommended to manage the lights in each scene shot using layers or groups, and to hide or remove unnecessary lights for the rendered shots.

You can turn on the “Show Statistics” feature to monitor the number of Lights. Please also send a screenshot of your preview window after enabling this option.
