'GenerateUV's failed, couldn't convert to a D3DXMesh'

[K7-Avenger]

Im also having the same issue with the latest UDK build.

Yeh I managed to fix this by changing AllowD3D10 to False ( i had set it to True previously) in the engine ini file. Seemed to mess a lot of things up that one.

which engine.ini file is that iv looked throuhg a load and it cant be found from search

UDKEngine.ini


but I have AllowD3D11 instead, but still its on false cant get to work can this depend on the static mesh of mine is very large?

When I switch my renderer from DirectX 9 to DirectX 11 by File -> Switch Renderer I had the same issue. And I can fix this only when swithc back to DirectX 9. Guys, do something with this please.

Just found this thread after searching, as I am having the same problem.

Same here. Is Epic trying to adders this issue ? Can we expect fix any time soon ?

That's the only available fix I know. I suggest Switch Renderer from 10 or 11 back to 9 works for me. Hopefully the issue will be addressed soon enough.

I've had the issue---but it's not a big deal. If that happens then I just go back into 3ds Max and do the automatic mapping for the lightmap UV there.

Same as above. DX11 renderer have no luck in generating UVs.

This issue is 2 years old and still exists? Wow..

I'm getting it while trying to create a fractured mesh.

Guess I'm dropping down to DX9.

[micahpharoh]

I just tried DX11 again today and it still has plenty of issues.

[Bellian]

Same problem here in DX11 mode.
Please Epic fix this problem.

if you have this problem, just create a light map in the 3d modelling program that you're using. I had this problem a few days ago, creating a light map in 3ds max and then importing it is more efficient than relying on UDK.

^ Not everyone has, uses, or even knows how to use third party programs.

It's an outstanding bug with the software and Epic should fix it.
