When working in 3D mode in Photoshop, rendering is an essential step to visualize the final outcome of the design. However, there are times when you may need to cancel the rendering process to save time and resources. Here are a few steps to cancel rendering in 3D mode in Photoshop:

1. Pause the Rendering Process: If you want to temporarily stop the rendering process without canceling it entirely, you can simply pause the rendering. To do this, go to the 3D menu at the top and select 'Pause Rendering.' This will halt the rendering process until you choose to resume it.

2. Cancel Rendering: If you wish to stop the rendering process completely, you can cancel it altogether. To do this, go to the 3D menu and select 'Cancel Rendering.' This will immediately stop the rendering process and allow you to make any necessary adjustments to your design without waiting for the rendering to complete.

3. Adjust Render Settings: Another option to consider is adjusting the render settings to decrease the quality or resolution of the rendering. By lowering the settings, you can speed up the rendering process and potentially avoid the need to cancel it altogether.

It's important to note that canceling the rendering process may result in an incomplete or low-quality preview of your 3D design. However, there are situations where canceling or pausing the rendering can be beneficial, especially when you need to make urgent changes or when the rendering process is taking too long.

By following these steps, you can effectively cancel rendering in 3D mode in Photoshop and optimize your workflow in graphic design projects. Remember to consider the impact of canceling or pausing the rendering on the quality of your design, and use these options judiciously to achieve the desired results.
