The main downside I found with D5 Render is that it can struggle with very large or highly complex scenes. When working on projects with a lot of detailed objects or large environments, the performance can slow down, and it sometimes leads to longer loading times or lag. Another thing I didn’t like was the limited customization options compared to other rendering software like V-Ray. While D5 Render is easy to use, it lacks some of the fine-tuning control that more experienced users might be looking for. Lastly, the asset library, though good, could use more variety and higher-quality models to give users more options without needing to import third-party content.
