Send to Unreal is broken in Blender 4.0 beta, FBX is corrupted/Missing data

funkysandwich commented 11 months ago

Hi. Upon using Push Assets in Blender 4.0 beta, the assets fail to be imported by Unreal, but in Blender 3.6 it works fine. An export using Blender's built in FBX exporter in 4.0 does import. Just not ones from Push Assets.

Snippet from Unreal output log on import

LogFactory: FactoryCreateFile: StaticMesh with FbxFactory (0 0 C:/Users/funky/AppData/Local/Temp/blender/send2ue/data/StaticMesh/Blender40ExportTest.fbx)
LogFbx: Loading FBX Scene from C:/Users/funky/AppData/Local/Temp/blender/send2ue/data/StaticMesh/Blender40ExportTest.fbx

Tested with Blender 4.0.0 Beta, and Send to Unreal 2.4.2

Same for Blender 4.1 I hope for a quick fix since Blender files 4.0 and above are not compatible with 3.65 anymore.

universalconquistador commented 10 months ago

Same for Blender 4.0 general release.

+1 Generated FBX for UE import flagged as corrupted. UE: 5.3.1 Blender 4.0.1

The very same file works fine with Blender 3.6.5.

grahamwheaton commented 10 months ago

Same issues for me. Blender 4.0/ UE 5.3. Was previously working fine with Blender 3.6

LiuYangArt commented 10 months ago

+1 having the same problem here. blender 4.0

eatmylazer commented 10 months ago

Glad to know it isn't my mesh. Almost had a heart attack here. Same to me.

Ondicknek commented 10 months ago

same here, fixed it by exporting the 4.0 project as an fbx and importing it into a 3.5 beta version.

Kingfelix23 commented 10 months ago

I think it is just the plugin that doesn't work. Exporting a fbx manually and importing it into unreal works

Ondicknek commented 10 months ago

yeah you could export without the plugin but its super slow and annoying

Kingfelix23 commented 10 months ago

Yes, of course, but why not just open the blend file in 3.6 instead and use send2ue as usual, no reason to export to FBX, or?

mlubich commented 10 months ago

The same with me. I had a look into the code and there seem to be some workarounds and fixes on how the 3.x series handled FBX exports. From what I see the original code (3.x) was copied and slightly altered/fixed and the original methods of the fbx exporter were overwritten during export. This for sure messes up the new 4.0 fbx exporter code. I did a quick test and reverted the overwrite and from what I see is that the export now works without any noticable problems so far. Maybe this observation helps to fix this problem.

LiuYangArt commented 10 months ago

can you share the fix version ? Thanks

I am a bit unsure what you mean. Did you change code in send2ue or in Blender itself?

mlubich commented 10 months ago

I am a bit unsure what you mean. Did you change code in send2ue or in Blender itself?

I did change the python code of the send2ue plugin.

The change I did is a crude hack, as it bypasses all the fixes/additions done by the authors of send2ue. There are certainly problems with this approach as I do not know what was fixed in the new blender FBX export code and which send2ue fixes are still needed.

Here is a comment from the io.export method in which the send2ue developers are describing the overall idea:

Note that this function imports the blender FBX addon's module and monkey patches
some functions to fix the scale factor and world origins of the objects, so that they import
nicely into unreal engine.

If you want to experminet yourself you can do the following:

Lets call send2ue_path the path were your plugin is installed (You find the path in blender in the preferences/Add-on/Pipeline:Send to Unreal)
Edit the file /core/io/fbx.py

Go to line 538 and 552 and comment all the lines were the original attributes are overwritten


#export_fbx_bin.fbx_animations_do = fbx_animations_do
#export_fbx_bin.fbx_data_armature_elements = fbx_data_armature_elements
#export_fbx_bin.fbx_data_object_elements = fbx_data_object_elements
#export_fbx_bin.fbx_data_bindpose_element = fbx_data_bindpose_element
...
#export_fbx_bin.fbx_animations_do = original_fbx_animations_do
#export_fbx_bin.fbx_data_armature_elements = original_fbx_data_armature_elements
#export_fbx_bin.fbx_data_object_elements = original_fbx_data_object_elements
#export_fbx_bin.fbx_data_bindpose_element = original_fbx_data_bindpose_element


Again, I do not think that this approach is a feasible stable solution. The original authors should have a look at the current blender 4.0 fbx implementation and decide if all any of fixes present in send2ue are still needed.

Kingfelix23 commented 10 months ago

Ok, cool. thanks.

I guess you dont know whether it was a specific attribute was the culprit, or do you have to turn them all of, or maybe that doesnt matter?

mlubich commented 10 months ago

No, I do not know. I just deactivated all of them just to see if this makes any difference. I only have one project I am transferring from blender to unreal, so that sample size to catch any problems is quite low :) I do not export any animations or armatures, just plain static meshes.

Here's a proper fix until addon is updated:

the fbx.py file mentioned above is what we need to change

go to line 35, add elem_data_single_char to the list so it looks like

from io_scene_fbx.fbx_utils import (
    FBX_MODELS_VERSION,
    FBX_POSE_BIND_VERSION,
    FBX_DEFORMER_SKIN_VERSION,
    FBX_DEFORMER_CLUSTER_VERSION,

    units_convertor_iter,
    matrix4_to_array,
    get_fbx_uuid_from_key,

    elem_props_template_set,
    elem_props_template_finalize,
    fbx_name_class,

Search for b"Shading" and replace elem_data_single_bool(model, b"Shading", True) with elem_data_single_char(model, b"Shading", b"\x01")

That's all!

I was having the same issue with the fully released version of blender 4.0 and this worked perfectly! Until the Send2UE devs manage to make a fix for this version of blender, this should definetely be the pinned fix. Thanks for figuring this out :)

vikista commented 9 months ago

Im like not getting any error but my exported mesh from blender to unreal is not updated when I press export. Even when I add new object to Export collection it is not exported. Any ide what can be with that?

Kingfelix23 commented 9 months ago

Well, it isn't working at all in 4.0 if you dont patch the file with the code AveryX01 provided. If you run earlier maybe the python setting isn't turned on, but it it isn't related to 4.0 you would probably be better of making a new thread

vikista commented 9 months ago

Well, it is a different version of Blender, mine is now 4.0.2.

@JoshQuake Have you had any issues with normals? I tried exporting Suzanne and the normals are off on some faces. In this case turning on smooth shading looks correct. In other meshes I've edited sometimes flat works, but smooth does not. I tried the different geometry smoothing options for Send To Unreal, but nothing seems to help.

Did you miss the comma when adding elem_data_single_char to the list? Maybe open console and see if there is an error.

I couldn't tell ya. I only went into the newer fbx io plugin to see what values could have changed. Only difference I saw was how Shading True was being set and it solved the crash.

I tried exporting a flat suzanne and rounded cube but I do not get the same result as you.

Blender 4.0.1

ld have changed. Only difference I saw was how Shading True was being set and it solved the crash.

Thanks for double checking for me. I guess something is wrong with my build of Blender. I'll try 4.0.1. Thanks! Edit: Thanks to JoshQuake for telling me I was missing UV info on my character which led to the shading issues.

Thanks for the update! This does fix the issue for me.

FYI: For anyone interested - not all steps may be required, but I was just being cautious.

Unzipped addon folder.
Found file and edited.
Zipped up folder (make sure not to have another folder level deep in the zip - zip file structure should match the original).
Removed the previous install of the addon from blender.
Closed Blender.
Opened Blender Installed updated zip.
Closed Blender and re-opened.
