Has anyone encountered this problem?
How was this resolved? I am using version UE5.7
Hello there @user_fedfffa8a9a9be6dbce4d6dde9e465b8fa5df9a62549e671d2d9cc !
Considering your main error, it sounds like a null reference:
Assertion failed: PlaneMesh.Object … MetaHumanFootageComponent.cpp [Line: 25]
UnrealEditor_MetaHumanImageViewerEditor
This is coming from the MetaHuman viewer component, the part that handles showing you the model itself in a 3D view. Said component is looking for a Plane Mesh, failing to find it, resulting in a crash. Unless this is happening with a particular metahuman, it means part of the editor is damaged.
So, first thing I would test, is verifying your UE install. From the launcher, check your install’s dropdown menu, and click on “Verify”. This will repair any and all componets in the engine.
If the issue persists, the next step is to ensure that all related plugins to MetaHuman are enabled in your project
Also, if you haven’t already, create an empty, test project, and generate a new metahuman from scratch. If that one works as intended, then the issue would be isolated to your active project.
At that point, you should clear said project’s cache, to eliminate any possible corruption. To do so, navigate to it’s main directory, and delete folders Intermediate, Saved, and Binaries. Once completed, re-open your project, allow it to rebuild, then test again.
