Why are the "import" buttons greyed out?

I was trying to import an FBX scene for a client to test it out, a skeletal mesh with animations but turns out it doesn’t let me, it seems to be stuck or “insistent” on importing animation and doesn’t give me the option to import as skeletal mesh or even mesh at all, then I tried with a different skeletal mesh with no animation, same problem.

I was checking answers and it was supposed to be solved on earlier versions of the engine, currently I am installing 4.12 to re-check if I can import onto that but it will literally halt any progress I can do with my projects if I am completely unable to test them in-engine.

I am having this same issue on 4.17.2 as well. All other solutions online say to edit the EditorUserSettings config file but that solution did not work for me. Were you able to ever find one? This bug has halted progress for me as well, what good is a game without being able to have our main characters? The attached image is for anybody else who may have a solution, here is the problem when trying to import.

I had to literally redo the whole rigging and export the standalone skeletal mesh without any control rigs, then proceeded to make the animations and export them, not sure what was the problem but is certainly not a great solution, on the other hand if you are trying to import animations and it doesn’t let you pick a skeleton (more likely if you are on win10) change your desktop settings to high contrast and see if drop down menus are back, it was a weird glitch present in 4.12.5 and I presume some earlier versions.

That’s so annoying you had to redo all that. I’m not even trying to import an animation right now, just the mesh with the skeleton and this is the first box that pops up. When I hover over the choose skeleton option, it tells me if I leave it as none, it will make a new skeleton which is what I want it to do. I enabled “animation” and “bake animation” in my export settings in Maya, since that is what the UE docs said to do. Any other way and UE has given me a popup box with the message “failed to import asset.” Thanks for your quick response, sounds like I may have to follow the same process you did if nothing else works. I’ll let you know if I do figure it out though, in case you come across this problem again

To alleviate the whole process try to salvage your mesh by exporting it to OBJ or other format and reimport to a new Maya scene, if it is a skeletal mesh you may want to also backup your weight maps and apply them onto the mesh, basically, try to rebuild your barebones mesh and then importing it again onto UE.

In blender when you export to .FBX you have to select the skeleton and then mesh and then export and check “Limit to selected objects”

Same issue in 4.27.2. FBX file is 100% correct, as it imports an works in other game engine.

Has anyone solved?
In Unreal 5.1 I have the same problem.
I import the fbx file from 3ds Max.

For Maya: unbinding my mesh, deleting history (Edit → Delete by Type → History), and rebinding the mesh worked for me.
