Heya,
Small bug. If you import a 3d mesh, then later, add a new uv set/channel, and re import. Unreal does not recognise the file has a new uv channel to import. Only way to get a new UV channel in is to delete and import from scratch. Applies to static and skeletal meshes. Tested with Max and Maya exports.
Easy to recreate. In your 3D package: Make a cube, unwrap it and import to UE4. Go back to your 3d package, make a second uv channel, export, and hit reimport in Unreal. It will not import your new channel.
Hi Daniel,
I just tried this and it worked fine for me in 4.15. Which fbx version are you using?
I just tried it fresh, this time in 4.15.1, and had the same problem occur. Testing with 3DS Max 2015, using fbx2014
I made a cube, set up uv 1. exported and brought into Unreal. Uvs correct. I then go back to my cube in max, add another UV channel, do something with it, and export over the original fbx. I hit reimport in Unreal, and the new uv channel is missing. As proof it’s the reimporter, I then imported that same cube fbx fresh to a different folder in Unreal, and it contains all the uv channels correctly.
Hey Daniel,
Sorry I’m not getting the same results, but I tried it again with Max 2015 and FBX 2014. Can you send me the two fbx files you’re using?
