Really excited that vray is coming to blender free with some *caveats but its really good license that allows you to learn the system. You can use it for commerical projects as well.

The only annoyance is you have to login to active the license once it expires.

The Community Edition is aimed at solo creators looking to build strong portfolios and handle small-scale personal or freelance projects at their own pace. However, it does come with some limitations. Render resolution is capped at 2K, and output is limited to 8-bit formats. It is also limited to local machine use, with no pipeline integration support.

Even so, this could be a practical option for beginners and independent creators. It’s rare for a major production renderer on the market to include a Blender edition that is free for commercial use.
