Unfortunately this tool seems to not work anymore, it throws an unhandled exeption Drawscale Failed to Parse while trying to convert a simple static mesh :

@Matt3D

thank you for the great tool but i have issue with my skeleton assest i can't export it maybe i doing something wrong

[Matt3D]

Fixed the broken dropbox link to v2.0 in the first post. Here it is again.
https://www.dropbox.com/s/w5e5phsldi..._v2.0.zip?dl=0

Also new link to the documentation
https://www.dropbox.com/s/h1f0vzntgo...ation.pdf?dl=0

Anyone who still wants the source code, just send me an email/pm

For those having issues with errors, please share the T3D from UDK you are trying to convert. And I'll look into it.

[WajeehMetalhead]

Hi,
I keep getting an actor not found dialog box whenever i try to convert a T3D File, Can anyone guide me further?
I exported a static mesh from UE3 and imported it into UE4 as a .OBJ file,
I have the source of the game in UE3.

[KAYD]

Hi Matt.
Can you share source code of your tool? Thanks

[Mycon7]

Thanks for making this tool! I've been on the fence about moving to UE4 for a while and this tool helps me test and prototype quickly.

The tool didn't work for me at first though, I kept getting an "Index error". After some trials going back and forth it looks like the issue was caused by the line: LODData(0)=(ShadowVertexBuffers=(ShadowMap1D'ShadowMap1D_4')) in my script copied from UDK. I was able to delete this line and the tool converted the script without any problem. It appears to have something to do with pre-built lighting, the fix is to select the objects you want copied in UDK, and then move them in the editor slightly to blast away pre-built lighting information, THEN copy them and use the conversion tool. After figuring that out, everything seems to work fine.

[DE4Dkiller616_MC]

It does not work for me

[Tuxmask75]

Ok so I got the editor to work , it seems that I did not run as Admin ! OMG.
Also Any way to get an update so the tool also keeps layers?
and there is also an issue with crashing Unreal 4.11 when the CustomProperties line is present.
I deleted the line and no crash happens.

I'd actually like to get ahold of the source for this tool so that I can make a few changes of my own.

[Tuxmask75]

Finally got all my assets into Unreal 4.10.4 and I tried to run the tool for the first time and I get an error, my guess is that it don't work with the version of Unreal 4 that I'm in.

Here is the error log:

Hey so I was able to convert everything from UDK to UE4 except SoundCues And ParticleSystems...I was wondering if there is a way to get those moved over like how Speedy37 was able to convert Materials?

Thanks in advance

How did you manage to do that ?! You transferred models, materials and textures over to Unreal 4 from UDK??

aww man ! well thx for the reply !

[Matt3D]

@DarkSynopsis on Twitter made me aware that there is an introduced bug in v1.2, only the first static mesh will have it's rotation converted over. This isn't a problem in v1.1, or here in v2.0

Although I don't know how useful it will be to anyone now, I am releasing v2.0 now for free. Not really any money to be made off it, and the Unreal Marketplace I don't think will ever support external programs like this one, and I don't have the experience to re-create the tool in UE4 naively.

https://dl.dropboxusercontent.com/u/...4Tool_v2.0.zip

v2.0 Fixes the introduced bug, plus adds Lightmap UV support to static meshes, and converts a whole range of actors including:
Lights, Cameras, Decals, Kactors, Skeletal Mesh actors, Interp Actors, Particles, Audio and Exponential height fog.

And now supports Dynamic linking of assets in UE4: If the UE4 content folder is provided, ported over assets only need to have the same name as they did in UDK, but can be located anywhere in the project's directories. If an asset with the same name is found it will use it. If no asset with the name is found, or no UE4 content folder is provided the asset path will simply be converted from

Hey guys , I'm looking to just convert over everything within a .upk over to Unreal 4's format including the upk's internal folder structure. is it possible with any of these tools ?

My tool only converts T3D script, not binary assets.

Hey Stridemann,
I was wondering if since your program uses Speedy37's plugin to first get things imported over and then I assume copy to a 4.6 build, if you wouldnt mind telling me how you got his plugin to work. I have gotten things to import over, not T3D but once they are in the editor, my scene doesnt fill up with the static meshes, etc. I only get 1 brush and 1 static mesh. I can't seem to figure out what I'm doing wrong. Once things are ported over I wanted to use your software to get the rest skeletal meshes, etc. Would you mind telling me how you got it to work? I'd greatly appreciate it.
