Hi, thanks for your answer. But I forgot to mention that I actually added the Reflection capture sphere. And no, I don’t think this is an intended behavior. Let me show you two more screenshots.
The top one has the object unselected. The bottom one has the object selected. Just by selecting the object, the reflections break. And by unselecting it, they return to normal. This never happened with previous versions of the engine. And this happens apparently just by enabling Force no precomputed lighting and building the level. And as I said, sometimes, by disabling antialiasing in a post-process volume affects too.
Greetings!
