See the Movie Render Queue's step for setting up your system configuration for details on how to adjust the timeout delay and recovery within Windows 10. It's possible to prevent, or reduce, occurance of these types of crashes by extending the time it takes for the GPU to timeout, giving it time to potentially recover without causing the engine to close. You will typically see a message similar to this: This type of crash impacts not only Unreal Engine but anything on your machine using the GPU. In situations where you have a complex scene that can put the GPU under heavy load can cause a timeout delay (or TDR) and subsequent crash to occur within Windows 10. The following are additional suggestions to best work with GPU Lightmass in your projects. Restart the editor for these changes to take effect. Under the Platforms > Windows category, set the following: Virtual Textures > Enable Virtual Texture Lightmaps Virtual Textures > Enable Virtual Texture Support Under the Engine > Rendering category, enable the following: Open the Project Settings window from the Editor > Project Settings menu: Under the Built-in > Editor category, locate and enable GPU Lightmass. Open the Plugins tab from the Editor > Plugins menu. To enable GPU Lightmass in your projects: This workflow is not possible with the CPU-based Lightmass system. Additionally, GPULM offers new workflows with interactivity that enables you to edit the scene, then recalculate and rebuild lighting on-the-fly. GPULM significantly reduces the time it takes to calculate, build, and generate lighting data for complex scenes, achieving speeds comparable to those of distributed builds using Swarm with the CPU-based Lightmass. However, using the GPU to generate and build lighting data means that we can leverage the latest ray tracing capabilities with DirectX 12 (DX12) and Microsoft's DXR framework. This system of baking lighting into textures is similar to the CPU-based Lightmass Global Illumination system. GPU Lightmass (GPULM) is a light-baking solution that precomputes complex light interactions from lights which have their mobility set to Stationary or Static, and stores that data in generated lightmap textures that are applied to scene geometry.
