I am reading over this light meter documentation and it doesn't mention how to initiate a visual representation of the lighting effect, which makes it seem like it should show up without further settings being edited. The light meter tool in 3DS Max 2018.4 is giving you a little trouble while using Mental Ray, correct? When you click the 'calculate all light meters' button, are there a few seconds of calculations running before nothing is displayed? You are working in 3DS Max 2018.4 using Nvidia Mental Ray for rendering in your scene.
Hello for bringing your question to the forums! I want to make sure I have all the information correct.
