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"

Instanced Static Meshes render with default material

Hey I have a problem with InstancedStaticMesh, the mesh instances are rendered with default material and I can't figure out why

what I did is:

opened a new c++ project just basic code, I've created:

c++ Actor class "Tile", declared UStaticMesh in it, I've created A blueprint from this class and set the static mesh and material, the material is created by me and it has the "Used with Instanced Static Meshes" flag set

c++ Actor class "MyLevel", declared UInstancedStaticMeshComponent, and a TSubclassOf in it, the "TSubclassOf" member is UPROPERTY that can be edited anywhere and it is set to Tile Blueprint that I've created.

In "MyLevel"constructor I create instancedStaticMeshComponent, in BeginPlay() I check if TSubclassOf is set and if I set the InstancedStaticMesh->SetStaticMesh() and just to test I also add instance of that mesh, and now the mesh is rendered but with default material and I have no idea why. Can any one help solving this problem ?

code from MyLevel class

and the result on left instanced static mesh with Tile_BP blueprint, on right Tile_BP blueprint dragged and dropped in editor https://onedrive.live.com/redir?resid=89D22DBC98E39077!1189&authkey=!ADUj0WUnAZ328qM&v=3&ithint=photo%2cpng

Can any one tell me why this is happening ?

1 answer: sort voted first

I've sorted the problem by adding a UMaterialInterface into my Tile class and loading my material in construction script than when I call AddInstance on InstancedStaticMeshComponent and get its index I call SetMaterial() passing in the instance index and the appropriate material

Update: Right now I only have a StaticMeshComponent in my tile class I have made a blueprint from it I set things as shown on pictures in my question but I call SetMaterial() on instancedMeshComponent passing in instance index and material of appropriate index that I get from tile class StaticMeshComponent
