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"

UE4 Crash on EXTREMELY SIMPLE skeletal mesh import

Hello! I am in the process of creating a Battlefield-like game, and I have just gotten to the stage of importing characters. However, evrytime I import, I get the following error:

Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:d:\build\++ue4+release-4.14+compile\sync\engine\source\runtime\core\public\Containers/Array.h] [Line: 634] Array index out of bounds: 0 from an array of size 0

I'm not sure how to access this drive, as I have a burning desire to investigate the code myself (bugfixing ii strangely pleasing).

Anyways, I hope someone can help me. I am importing from blender, it's literally a 14 bone, no-more-than-100-polygon roblox-like character model, and I believe I'm exporting with proper settings. No animations have been made for the model yet, it is however skinned. I tried exporting and importing armature and mesh seperately as well and this had no effect.

Any and ALL help is appreciated!!!!!!!! Thank you!

The full log is as follows:

Oh, I should add, it is easily reproducible. On an also related note, there was an instance or two where it simply "failed to import see output log for details" rather than crash, though I'm not sure I can reproduce that...

Thanks man good to see others have it too :P.

I'd like to confirm that 1 armature/bone skinned to a cube (no more, no less), instigates he exact same crash.

Same PROBLEM in 4.14.3.

AND IT HAVE MATERIALS.

KuroSekaie, have a look at this thread:

https://answers.unrealengine.com/questions/548029/importassets-commandlet-crash-when-using-nosourcec.html

The bug report is about source control but the first comment talks about the AllowCommandletRendering flag which might help.

This is probably UE-38935 Crash with FBX Import as Skeletal Mesh. Crash happens when you import a skeletal mesh with no material.

https://issues.unrealengine.com/issue/UE-38935

This issue is fixed and I think the fix will be in 4.14.1.

Thank you so much! I'll try out a material and see what happens... thanks!

The materials fixed it for me btw! Thank you! (I know its been a while)

Same thing happening to me. Trying to import a very simple skeletal mesh with 10 standard bones from 3ds max with a skin modifier... I've tried max 2017 and 2016, rearranging and animating bones, different FBX export parameters and different import parameters inside Unreal. Same outcome: Crash
