Unreal Engine 5 - Tips

You should enable DirectX 12. Edit - Project Settings - Platforms - Windows - Default RHI DirectX 12

Unfortunately, at this moment, Unreal Engine 5 doesn’t support nanite for the static meshes which have transparent material.

Because modular buildings can have interiors (it could have transparent material such as glass), the modular building models don't have Nanite enabled as default.

If in your project you’ll use the buildings only for exterior, you can enable nanite manually for all the modular buildings models.

If you don’t enable Nanite for the modular pieces and you have in your project the “Virtual Shadow Maps (Beta)” enabled, you have a chance to encounter this visual error:

You have some alternatives to solve this problem:

“Nanite geometry always renders to the Virtual Shadow Map regardless of distance, since this is the most performant option and provides the highest quality. It is possible to make non-Nanite geometry behave the same way as Nanite by the console variable” r.Shadow.Virtual.UseFarShadowCulling 0

OR

Disable “Virtual Shadow Maps(Beta)” and switch to Shadow Maps:

Edit - Project Settings - Engine - Rendering - Shadows

OR

Enable Ray Tracing Shadows:

Edit - Project Settings - Engine - Rendering -Hardware Ray Tracing
