[UE4] Normal problems when exporting from Maya
Hello everybody,
as probably many of you I'm currently testing the new awesome Unreal Engine 4. In the last week I tried to have an overview of the new amazing features. Today I started to import some assets from Maya and I'm having some big issue. Basically, when I try to import static meshes with the "import normals" option I get horrible results. I have some big "black spots" lightning problems, the same one you could have with soften edges and bad lightmaps in UDK.
Let me first say one thing: all the mesh I tried, were coming from a project in UDK where they're all displayed correctly. So it is not a problem of light maps or reversed normals.
Now let's get into some details:
1) If I export the mesh with soften edge normal configuration from maya, I get really horrible results: big black artifacts even with VERY SIMPLE meshes (a slightly curved plane, for example).
2) If I export with harden edge configuration from maya, the result is SLIGHTLY better: big black artifacts are still there.
In both the examples, obviously, the "imported normal" option was turned on during the FBX import process in UE4.
3)If I compute the normals in UE4 during the import process, I get correct results but I cannot achieve the useful "smooth" effect of the maya soften edge configurations.
I'm very worried about this problem because I tried several different meshes without achieving good results.
I'll stress this one more time: each single mesh comes from an UDK project where they're processed correctly, so I assume that something changed in the export/import process and maybe the workflow could be slightly different.
Have you experienced these issues in this first week of UE4?
Thank you very much, once again, for your help,
Fabio.

Could you post some images for us to look at? Maybe a screenshot of the artifacting, a sample normal map, a screenshot of the low-poly mesh, and maybe some screenshots of the import/export workflow? Unfortunately, There's simply not enough detail in your post without good visual aids to see where the problem might be occurring.
Thank you very much for your attention, I really appreciate it.
