Last week I did a post listing some of the external renders available for Blender 2.6 and how they can help us to produce quality architectural visualization with Blender. And this week I found out that another big commercial render has now an exporter for Blender. I`m talking about Maxwell Render that doesn`t have a large user base like V-Ray, but is well known between architectural visualization artists as a fast and powerful render engine.
If you want to try it, just visit this link to download b-maxwell. Of course, you will need Maxwell Render as well.
