Yeah, upload the project. I’ve encountered this kind of shadowing problem(s) before in my scenes, and it varies as to how to fix it. One thing to ensure is the Project Settings are correct for what is in the scene, and the quality level is either High or Production. Preview and Medium tend to result in these types of shadowing problems being more pronounced. Another is mesh distance fields, and the settings for DFAO and DF Shadowing (or DFS in short). I’ve simply encountered it in several different cases of using meshes, none of which were instanced from a blueprint either. So, I think there’s a common theme / thread of error among them all.
