Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

BUG 4.10.4-4.11.0 Reimporting LOD adds garbage Mat.ID

Hello in short, When you import LOD levels in Static Mesh editor its all fine, but when you Reimport any LOD level as a result it creates an additional Material ID slot. But you cant see that in the Static Mesh Editor, instead you can find this when you place a mesh in the world. Heres' some screenshots: Mesh have 3 LODs +Base. Which means 4 Mat ID's: alt text alt text

But if I dare to re-import any existing LOD level i get this: alt text

And the problem is that Static mesh editor doesnt show this but if you place this mesh into a BP or just in the world you will see that there's a new Mat ID for that mesh which does nothing and if process of reimporting would repeat the system add another Mat ID to the mesh... Very annyoing and easy to reproduce.

Is this related to same issue where LOD reimporting causes whole LOD mesh to disappear?

Hey Jenny Gore,

These two could be related, but I cannot say as I do not have a repro case for the issue you are reporting. If this is an issue, could you please create a new AnswerHub post and provide the steps there so we can report a separate bug for this issue?

Thank you,

Andrew Hurley
