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"

Empty train from the inside

Hello I don't know why, but when I click to mesh or I placed the mesh on level then doesn't work properly. If I go in mesh then there is no walls and other things.

As you can see left side in blender and right side in Unreal Engine 4.15. I don't understand why this happening.

Here is the asset if this is easier to understand.link text

If I import in blender the fbx file then it shows correctly but not in unreal engine.

Try setting your materials to 2 sided, if the poly share both an inside and outside..side they will work correctly once you set your material to 2 sided:

Also just a side note 84 materials is a lot of materials and draw calls for a single mesh, you may want to try to consolidate them or do an optimization pass for them, just FYI.

I would imagine the issue here is that your normals are flipped, I can't remember how this is done in Blender, but you should have an option such as flip faces, or flip normals. Obviously not all those faces need to be flipped though.
