Development Getting Started & Setup

I have a fresh install of Unreal 5.3.1.
I went to “Games → Blank”.

I get this error “Landscape 64 actors with physical materials need to be rebuilt”.

This is a screenshot of the new project:

I jave exactly the very same issue and there is absolutely no accurate solutions to sort this issue out. I jave tried every single build option from the UI and watched and read hundreads of videos and articles but there is nothing that helps.

I get this with any landscapes.
It seems to disappear after Play.

Just a bug with the error message is my guess, if physical material have been built.

I agree with Astaraa…just play the simulation once and the message will go away
I had the same error and it disappeared as soon as I started the game
