Fbx imports failed from blender 2.77

Development Asset Creation
1

I did a couple of blender item models (mostly, weapons). Now I got a little problem with it, when I try to import them, I’m getting Failed to Import …/file.fbx. Failed to create asset …/file.fbx .
In my error log, I have the following errors:

Can someone help me solving them please? I’m using Blender 2.77 version.
Note: All items are high-poly.

I can’t say I’ve had this particular problem, but I’ve had difficulty in getting fbx’s working before now and would be happy to try and help find the source of this problem if I can. Can you help narrow the problem down a bit? For example:

  • Have you successfully imported any models from Blender into UE4 before?

  • Do you get the same error if you try and export just a plain, UV-unwrapped cube?

  • What fbx export settings are you using in Blender?

  • Are the models you are trying to import just meshes? Or do they have armatures?

  • Do the models have any modifiers on them?

Are you trying to import all the weapons created as a single FBX (aka static mesh) in unreal?

Shouldnt you be exporting individual selected obj as their own FBX in blender?

The export as FBX in blender has a checkbox for selected obj, make sure that is ticked before saving the file.

Hello. @pickersZ yes, it is checked. I’m exporting individual weapon as an fbx file, and after it, importing them in ue4. [MENTION=35966]Happy Red Lion[/MENTION]

  • Yes I did, I think it was previous blender versions, but I did imported a couple of weapons successfully in ue4, without any error, I did the same for this items, but it failed :frowning: this time.
  • Didn’t try, will try a bit later today, when I get home.
  • Basically default ones, with mesh checked only on export (not all of them)
  • Just High Poly meshes
  • Subdivision, Solidify, Materials (not really a modifier) and Mirrors

I’ve spent a little time with Blender (2.78) trying everything I can thing of with combinations of subdivision, solidify and mirrors to try and get the same error but can’t do it. Its a curious problem!

  • Do try and see if you can import a normal cube without any problems. If this works, then move some of the vertices of the cube and add the modifiers you’ve listed and see if it still works. This will tell you where the problem probably lies, i.e. is the problem with your particular weapon model, or is it with the exporting-importing pipeline as a whole?

If you can import a cube fine, even with the modifiers on it, the problem is therefore probably with your weapon model…

  • save a copy of your weapon model, and simplify it; by deleting bits can you produce something that does export well?

  • if your weapon model is made up of multiple objects in Blender (which it looks like it might be, as your screenshot lists a problem with 8 different named meshes), is there any parenting going on within the model?

  • can you take a few screenshots of Blender to show the geometry of your model and how the parts of the object are combined?

  • when you say high poly, just how high do you mean… ?

(If you’re happy to put up a Blender .blend file for one of the weapon models you’re having trouble with, I’d be happy to look at it and see if I can see any problem.)

I am 2.77 user and I had no issues (fingers crossed) getting static and skeletal meshes from Blender to UE4 using FBX.

Currently I’m unable to upload my blender project, but if it helps, I can upload 1 project from those that I tried to get working, so it would be easier for debugging.

If you can upload any .blend file with contents that produce the same error as the one you describe, that would be fine. It doesn’t have to be your main Blender project. Presumably you have the same problem for each project you’re working on, so any project that generates the same error should help in tracking down the issue.
