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"

Cannot set LightMapResolution neither LightMapCoordinateIndex on fresh imported mesh.

I've imported some fbx files using

 FAssetToolsModule& AssetToolsModule = FModuleManager::LoadModuleChecked<FAssetToolsModule>("AssetTools");
 TArray<UObject*>  ImportedObjects = AssetToolsModule.Get().ImportAssets(files, myPackageName);

I cast them to UStaticMesh and apply materials without problem etc UStaticMesh* sm=Cast(ImportedObjects[m]);

But this two values are ignored ie

 sm->LightMapResolution = 128;
 sm->LightMapCoordinateIndex = 1;

When I open it on the editor coordinate index has been reset to 0 and lightmap resolution to 64 (default values)

I tried several things like

 sm->Build();
 sm->SaveConfig();

But I had no luck, I'm driving totally nuts with this.
