Reimport LOD level bug

Development Asset Creation

After importing a LOD for a static mesh, if you try to replace it by selecting “Reimport LOD level 1” in LOD settings group, new mesh is rendered on top of old lod mesh,and triangle and vertex counts show sum of both models. Also there seems to be no way to remove a lod level once you have added one.

Binary Build - Version 4.0.1-2027741

Step to reproduce:

Import a static mesh - for sake of example SM_Mesh1.fbx
Open mesh settings dialog and under LOD Settings, select ‘Import LOD level 1’. select a lod mesh - say SM_Mesh1_LOD1.fbx
Make a note of vertex count under LOD1 group
Now select ‘Reimport LOD level 1’ and import a different mesh (or indeed same one), say SM_Mesh1a_LOD1.fbx
Note that two LOD models are rendered on top of each other, and vertex count for LOD1 is sum of 2 meshes.

Hey mungobob,

Thanks for your report! I looked into issue and was able to confirm what you’re seeing. It looks like it’s a reporting error; number of polygons is not actually increasing but editor is telling you it is. I have written a report for this behavior.

Thanks again for report!

Thanks. view is definitely drawing both meshes on top of each other too though.
Also it would be handy to have a way to remove a lod entirely once you’ve added one.

Yup just encountered this I can’t believe there is no way to remove a LOD other than delete whole asset and start again!
