'Generate UV's failed' error
Hello. I am getting. Generate UVs failed. Couldn't convert to a D3DXMesh. HELP. The model has been made in sketchup and used in unity pro. And then i imported from unity to unreal engine 4 and when rebuilding lightning i got a error about UVs found internet that to fix it i need to generate UVs but i am getting error. If someone can please fix this model for me. Or tell me how to fix it. I am begginer in UNREAL ENGINE 4. Model link: CLICK ME MEDIAFIRE
So I was able to reproduce what you are talking about, but it seems you have way too many individual components on your command center. You need to break things apart that are meant to be represented as their own mesh. For example your satelite, the computer screen, and the machine components inside of your house need to be on their own seperate 0 to 1 UV space.
Because everything is being pushed on one lightmap, it cannot effectively generate an effecient UV for your static mesh so it continues to default to 0. Try dividing your mesh up by type, like the house structure, the satelite, the computer monitor, and the internal parts to get the correct results.
Here is some helpful documentation on how to optimize your models so when importing them into the engine, they are clean.

So the only files we are compatible with for static meshes are .FBX and .OBJ file types. If you are using SketchUp to export your mesh, there is an option to export it as a .FBX file. Keep in mind that if you are scaling in centimeter in SketchUp then it should work fine because it transfers over to the engine properly.
Here is some documentation on how to work with .FBX files once you have them exported:
Hope this resolves your issue.
