How can I optimize physics in Unreal Engine?

How can I optimize physics in Unreal Engine?

To optimize physics in Unreal Engine, you can reduce the number of physics objects, use simpler collision shapes, and adjust the physics sub-stepping settings.

What are the best practices for using collision shapes?

Best practices include using primitive shapes like boxes and spheres for static objects, and avoiding complex meshes for dynamic objects.

How does the physics sub-stepping work?

Physics sub-stepping allows the physics engine to simulate more accurately by breaking down each frame into smaller time steps, which can improve stability.

Can I use LODs to help with physics optimization?

Yes, using Level of Detail (LOD) can help by reducing the complexity of physics calculations for distant objects.

What tools can I use to profile physics performance?

You can use Unreal's built-in profiling tools like the Stat Physics command to analyze and optimize physics performance.
