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"

Blender to Unreal Engine 4 - fbx. visual problem

Hey guys, Im having kind of an issue when importing an fbx. file from Blender to Unreal Engine. I've made a bucket in Blender and imported the file in Unreal Engine. Looked completely fine in Blender from every direction. However, when I drag it into a level, only the front side is visible and the back side cant be seen. And no matter from which direction I'm looking it's always the same. And I got the same problem with a house I've made in Blender. When I look into the house I can see through all of the walls in the back. However when I look from behind the walls can all be seen, it's just when I look through a specific point of view and I dont know how to fix that.

If anyone has got a clue please help me, would appreciate it. Image files are attached below.

In your UE4 material editor, select the main material node and to the left of the window, check "Two Sided".alt text

And of course make sure to assign the new material to your object :) also, your bucket is fine with the normals on the outside.

In blender, you can see the normals by pressing "N" in Edit mode, and selecting which normals you'd like to see. alt text

Sounds like your Normals are flipped on the affected faces.

In Blender go to Edit Mode, select all your faces and hit Ctrl-N, Enter and then re-export it.

This should recalculate the normals on all your faces to make sure they face "outside" (and thus become eligible for being rendered on the screen).

Hope this helps!

Hey, first of all thanks for your help. I just followed your advise but it seems like it just does the opposite if I check 'inside'. Now I can see the back side while the front side is invisible. Same with the house, works fine now if I watch inside it but cant see the walls from outside. Could it be something with the export/import settings?
