Rigged n skinned vehicle model - maya to fbx - unreal engine :(

Mcbeardo

Hi

So i made a model, its a truck, i rigged it, and well its pretty much done. 

The rigging is just 7 joints, 6 wheels and 1 root, no animations since unreal is gonna do that for me.

Problem is, when i export the model with fbx. the file get very small. it should be like 20mb, but is 300kb. 

When i open it in unreal, it says it couldn't open it. 

"LogAssetTools:Warning: Failed to import 'M://Truck/Exported/Butt6.fbx'. Failed to create asset '/Game/ThirdPersonBP/Mesh/Truck/Butt6'.

Please see Output Log for details."

And that was the output logs details. Nothing else. the model doesn't even appear in unreal. 

SOO,  its from maya to fbx the issue is located. 

Its like it does not wanna export the skinned geometry in the fbx.

Any ideas on this subject would be great!
Thanks in advance!

okay first I would open the 300k file to see what if anything is in there. Then I would check my export settings... good? maybe... I would then try to export just the mesh, (kill the rig, just use the mesh no weights) and see what the file does. Does the mesh export? No, try to export a box. No? make a new scene export the box... If the box works, single bone weight the box, export. Basically trouble shoot down until you get to the simplest combination; less moving parts, less there is to break, easier to figure out. Good luck!
