Some errors appear when I export creature project as .fbx file
I export my creature project to a .fbx file and import it to unreal. I get some errors. What cause this problem? I have some bones with zero weight. Is this related? How to solve the smoothing group issues? the warns about smoothing group always appears.

Hello yes,
You need to make sure that every vertex is at least assigned to a bone and weighted as such. In rigging mode, regions that have not been weighted are highlighted in red.

What about the smooth group? I import a .fbx without any bones with zero weight. the warning about "Smooth warning" is still there.

Hello,
From the warning msg it looks like an issue with the vertex normals. Creature meshes are flat 2D meshes so I am not sure if smooth vertex normals applies to this case.

the error message(I deleted all bone with zero weight). So how to solve? what is smooth vertex normals?
Re: Some errors appear when I export creature project as .fbx file
Hello,
I believe the smoothing normal is an additional flag or dataset that has to be added to the FBX file on export. Right now Creature does not export such information because as I mentioned before, each mesh is treated as a flat planar mesh so you don't really need to infer what the normals are.
Is this actually causing you any import errors? Because as far as I can tell, this is a warning, not an error. I also tried importing a Creature FBX file from my end and the animations all display correctly. I can look further into what smoothing normal are when I get the cycles but so far, I don't think this is preventing you from importing Creature FBX files that play their animations correctly in UE4.

OK. Thank you very much. I'm just worried that this warning will cause a bug or crash. So, if this is just an Unreal warning, I'm not worried any more. thanks.chong wrote: ↑Mon Jun 26, 2017 6:42 amHello,

I will take a look at this warning when I get the cycles and do some more research in the FBX format to see if I can find any resolution to it.
