If you are a freelancer and deliver a client a render made with a cracked TPcrew version, you have a problem. Lumion sometimes embeds a "watermark of shame" invisible to the naked eye but detectable by metadata checkers. A savvy client or agency will scan your file. If they find it’s from a cracked copy, you will not only lose that client but also your professional reputation. Furthermore, any commercial work created with pirated software is illegal to sell—you have no commercial license.
