Exporting FBX loos vertex normal out from original imported FBX file as an example. #66537

Short description of error
Exporting FBX loos vertex normal out from original imported FBX file as an example.
Exact steps for others to reproduce the error
FBX lost custom vertex normals
Bug fixing is important. Since Maniphest blender/blender#57673 closed and archived, I try letting you know how important is for us to export to Substance Painter, Unity, Unreal (FBX) to paint ower models:
Enclose you will find .blend file, original FBX with correct normals, the Blender output FBX.
Here there is a related question to a forum that includes screenshots:
- Import original FBX into Blender
- Select the object MESH to export
- Export FBX using the default setting
- Open it in Painter, Unity, Rhino, Unreal or your other 3D soft tool
- Apply material with reflection to inspect the problem
- You will notice that vertex normals are not the same as in Blender and make the Blender object unusable.
NOTE: Please contact Rhinoceros or Unity so that they can help you with the FBX exporter.
You are not exporting with default settings, you are exporting with
Smoothing set to
Edge, to keep proper normals you need to export with
Normals Only instead (wich is the default value…).
I Keep proper normals you need to export with Normals Only and loos vertex normal.
As a workaround do not use FBX use OBJ until this is fixed.
Thanks, developer read this thread.
I'm not the only one having this problem. And this issue has been reported before.
Is the second time that they close this without verification with a general answer. I suspect they presume I exported changing settings (I hope that they do not do it on purpose).
Please double check using the files.
The file provided is there so that developers can look to the difference between the two FBX.
