When working with 3D modeling and viewing software, many users wonder if it's necessary to let the 3D viewer run in the background. While there is no strict rule about this, there are a few considerations to keep in mind in order to ensure the best experience when working with 3D models.

One of the primary reasons for letting the 3D viewer run in the background is to allow for smooth and efficient rendering of the 3D models. When the 3D viewer is running in the background, it can preload and cache necessary assets and data, which can significantly improve the performance when you access and interact with 3D models.

Another consideration is related to multitasking and productivity. By keeping the 3D viewer running in the background, you can easily switch between the modeling software and the viewer without experiencing delays or interruptions. This can be particularly beneficial when working on complex 3D projects that involve frequent model revisions and adjustments.

Additionally, some 3D viewers offer features such as real-time collaboration and synchronization with cloud-based storage, which may require the application to run in the background in order to ensure seamless communication and data transfer between users.

However, it's important to note that keeping the 3D viewer running in the background can consume system resources, especially memory and processing power. If you are working on a computer with limited hardware resources or if you often experience system slowdowns, you may want to consider closing the 3D viewer when it's not in use to free up resources for other tasks.

In conclusion, whether or not you need to let the 3D viewer run in the background depends on your specific workflow and hardware capabilities. If you frequently work with 3D models and require smooth and efficient rendering, keeping the 3D viewer running in the background may be beneficial. However, if you are concerned about resource consumption or if you experience performance issues, you may choose to close the 3D viewer when it's not needed. Ultimately, it's important to find the right balance between performance and resource management when working with 3D modeling and viewing software.
