Hi! Maybe somebody knows what to do. I installed last demo version of Corona. While 3ds Max doesn’t see materials in material editor, they are just black… Please help me(( ![2015-03-16_12-34-31.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/f/2/f2ac69288d53bd3b233094fe26decd1db05ce477.jpeg) ---

Hi, if Corona is set as renderer properly, then it is probably inactive license: [https://coronarenderer.freshdesk.com/support/solutions/articles/5000568654](https://coronarenderer.freshdesk.com/support/solutions/articles/5000568654) Also see these guides, as you may encounter some of these problems: [https://coronarenderer.freshdesk.com/support/solutions/folders/5000219434](https://coronarenderer.freshdesk.com/support/solutions/folders/5000219434) Hope it helps! ---
