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"

Import FBX: Material IDs incorrect?

Im made screenshots that show the problem better than me trying to explain it. Basically I'm trying to import a static mesh with two materials on it. I assigned the material IDs in 3DS Max but they seem to make it over to UE4 only partially correct. I am using the workflow as described in the UE4 docs, creating a MultiSub-Object.

What am I missing?

Export problem

EDIT: After remodeling the mesh, the problem fixed itself. Still not sure what caused it in the first place though.

EDIT 2: It seems that manually triangulating the poly before exporting the fbx, fixes the problem. So maybe the automatic triangulation messes things up somehow.

Hi, I have found a workaround:

  1. Create a new object, anything, a box or a sphere.

  2. Convert the new object to Editable Poly.

  3. In the new object, click Attach and select the mesh with ID problems.

  4. Select by Element and delete the new object.

  5. You will need to fix your pivot and probably Reset the Xform of your mesh.

  6. Export!

I hope it works for you too.
