Development Getting Started & Setup

This is actually in UE5.0.1

When I make a mesh in modeling tools and export it, then reimport on a asset LOD it crashes the editor. (ive tried deleting it before reimport as well) This is the error I receive.
Assertion failed: Addr < GetData() || Addr >= (GetData() + ArrayMax) [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 1527] Attempting to use a container element (000008016B15CBC0) which already comes from the container being modified (000008016B15CBC0, ArrayMax: 1, ArrayNum: 1, SizeofElement: 288)!

Hi ThreeTreeDog,

Have you tried importing it just as a mesh? Then you can use the Add LOD option in the ContextBrowser menu (or copy/paste LOD in 5.0 but I haven’t tried that)

I have it sorta figured out, I managed to get it in, I removed the material before I deleted the LOD, save asset, save level, Remove LOD, Save, added generated level 3 lod, then reimport lod 3… Not sure what step it was but seemed to work… It just started having a issue when I decided to use the modeling tools to make it… Think I did bake in the material.
