Hello everyone, it’s been three days now that I’ve been trying to export my project, but I can’t do it for the following reason. I’ve tried everything, but with no favorable results for the situation. The error that follows is UATHelper: Packaging (Windows): LogWindows: Error: appError called: Assertion failed: Mesh && Mesh-\>GetRenderData()

Thank you so much but I had already seen that post, unfortunately, none of the solutions have fixed my issue. I’m searching for a solution, but I can’t find anything helpful. I don’t know what else to do. ---

Do you know what Level is problematic? If no, then isolate them 1 by 1. Try to package the game without one of them. Find the problematic map and we can go from there. ---

Unfortunately, I don’t know which level is causing the issue. I’ll try this solution, thank you very much. ---

Be aware that the problem might be on multiple levels. ---

Maybe it could be Nanite, but I’m not sure. The fact is that it keeps giving me the error even though I’ve already applied the solution of disabling Nanite in the Landscape. ---

In the end, I managed to solve the problem. The error was caused by the fact that the package didn’t have the maps to export. So, I went to the Packaging Settings and found the map list, and only then was I able to export the project, which now works perfectly. Anyway, thanks for the help.
