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"

Custom FPrimitiveSceneProxy and rendering

Hi,

I have a custom FPrimitiveSceneProxy class and I am implementing GetDynamicMeshElements method.

I would like it to draw a shaded box so I have the following lines:

 auto MaterialProxy = GEngine->ShadedLevelColorationUnlitMaterial->GetRenderProxy(IsSelected(), IsHovered());
 auto ColoredMaterialProxy = new FColoredMaterialRenderProxy(MaterialProxy, DrawColor);
 
 Collector.RegisterOneFrameMaterialProxy(SolidMaterialInstance);
 GetBoxMesh(LocalToWorld, BoxExtents, ColoredMaterialProxy, SDPG_World, ViewIndex, Collector);

This draws the cube correctly, however if I change the render proxy to use GEngine->EditorBrushMaterial instead it stops drawing.

I guess I don't understand why that's the case, and would appreciate some advice.

Thank you!
