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

**Chaosrik** · 12-27-2009, 01:17 PM

Whenever I try and generate unique UV's on my mesh it fails saying 'GenerateUV's failed, couldn't convert to a D3DXMesh'. It does this for any mesh, even a simple box! Also does the same when I try and slice fractured meshes and also does the same for Unreal's own meshes. Can anyone help please.

Anyone at all..........

**eosteric** · 03-02-2010, 08:54 AM

I get this too. What gives?

**skasteve** · 03-02-2010, 11:57 AM

What is your system specs and operating system?

**eosteric** · 03-02-2010, 01:34 PM

My specs are Q6660, 8GB RAM, Radeon 3870, Windows 7 64bit.

February UDK build.

I get around the issue by just making a second UV channel in my 3D app of course, but still curious as to why the function doesn't work, as it could be handy sometimes. If the results it generated are good enough for some lightmaps.

**kernersvillan** · 03-02-2010, 02:44 PM

What are your exact repro steps in order to get this issue? What 3d program are you using, importing methods, what are you doing after getting the mesh imported into UDK, ect... The better the steps are listed out, the easier it will be to find what is causing this and fix it!

**eosteric** · 03-02-2010, 04:28 PM

So far it's happened on all meshes for me, but I just did a quick, simple, cube test now, as few steps as possible.

I just made a cube in Modo, no UVs (it says 2 uv channels once imported, no idea why).

Exported the cube with UnrealASE Exporter for Modo v1.08

Imported ASE from content browser, the dialog box that pops up on import I just hit ok.

Then I go to static mesh properties and hit generate unique uvs, and ok, doesn't matter which channel I try. Then the error message pops up.

**kernersvillan** · 03-02-2010, 05:09 PM

Ok, thanks. We will try this method with Modo and get back to you!

**Chaosrik** · 03-02-2010, 05:50 PM

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.

**eosteric** · 03-02-2010, 06:58 PM

Aha, thanks for the tip, I think I might have that set to true as well.

EDIT: Yep, that was it.

Does it do anything at all? Visually? The D3D10 setting

**Chaosrik** · 03-02-2010, 08:19 PM

Tbh I haven't noticed anything special, I was trying to get AA to work a while back and turned it on. But it seems to cause all sorts of probs (including crashing the editor with latest Nvidia drivers) so I turned it back off.

**eosteric** · 03-03-2010, 09:07 AM

Could we get an official response as to what setting D3D10 to true does? If it actually changes visuals in any way, or any performance optimization?

I searched the documentation and couldn't find a single mention of DX10...

**micahpharoh** · 01-07-2011, 04:16 AM

I know this is a really old thread, but I'm having the same problem. I never had any problem with it before, but I've changed PCs, version of 3ds Max, and even the version of the UDK, so maybe one of those things has something to do with it. Anyways, it'd be nice to have a fix for this.

**Don Punch** · 04-22-2011, 07:38 PM

Bumping this topic.

I am having the same problems when i try to create a unquie UV for my fractured meshes. I also tried on a 6 sided block and got the same results.

The settings have changed in the March 2011 UDK to D3D11 but the error name is the same. Any help would be great.

This has become a real problem for us, as we cannot use APEX desturction with DX11, & now we can't create UV's on fracture meshes. Even when i import the ase lightmap mesh from max, it doesnt work propperly.

Bump for same issue. here is my dxdiag

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

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.

**Shindawg** · 10-06-2011, 12:31 AM

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

**b43m** · 10-26-2011, 10:38 AM

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.

**darthviper107** · 10-28-2011, 10:57 AM

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.

**Raneman** · 12-07-2011, 09:04 AM

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

**DAOWAce** · 01-27-2012, 09:59 PM

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** · 01-28-2012, 12:23 AM

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

**Bellian** · 04-02-2012, 06:12 PM

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

**daem0nz** · 04-02-2012, 06:18 PM

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.
