Here's How To Fix Cloth Physics For Cinematics With Unreal Engine 5

Technical Artist Beatrice Schmidt, whose amazing projects were featured on our site in the past, like this cool vehicle rig set up using Unreal Engine's Control Rig, has shared a new valuable tip for Unreal Engine artists.

As someone heavily involved with cinematics and utilizing the Movie Render Queue tool in Unreal Engine, Beatrice encountered a well-known issue for those familiar with rendering: physics not functioning correctly when sub-samplings are enabled.

However, simply disabling sub-sampling is not an option when working with cinematics, since they're essential to eliminate motion artifacts in fast-paced scenes, minimize the effects of temporal aliasing, apply motion blur, and generally enhance image quality. Beatrice has found a solution by caching clothing and hair directly within Unreal, allowing her to use the desired options in the Movie Render Queue later.

This workflow is a mixture of the Chaos Cloth and the Take Recorder tool, and in the video above you can see a cloth simulation test, showing both the cache inside the Sequencer and a quick render done with a Temporal Sample Count value of 64.
