UDK crashes during UV-import

[Nick1236]

hello,
my UDK crashes during UV-import. My UV-resolution is 4096x4096. If i try to import an UV with 2048x2048(or other power of two resulutions) it works.

UVs do not have a resolution. It's all in the texture maps.

you know what I mean

[Graylord]

Actually no, I have no idea what you are talking about.

Max image resolution in UDK is 2048x2048 anyway.

to be honest a 4096 texture should import ok, check the format that your using and the texture LOD on import
i use the Targa (tga) format

[Graylord]

Yes, it should import, but it will be converted to 2048x2048, so it's pointless.

I've always used .PNG and never had any issues with it though.

All my character textures are 4096 by 4096. I know this was the max at one time, but I think it has increased since then. They are not converted to lower resolutions as long as you make the proper adjustments in BaseEngine.ini, such as:

TEXTUREGROUP_Character=(MinLODSize=1,MaxLODSize=40 96,LODBias=0,MinMagFilter=aniso,MipFilter=point)

What are your system specs?
I always use .tga but it shouldn't matter.

Also, UVs do have a resolution. Default resolution is 16bit, you can check Use Full Precision UVs on your mesh to use 32bit Uvs instead.

Thanks for your replies. Ive tested it with several formats, such as png tga and bmp. Also with several LOD-settings.

What are your system specs?

My PC specs are: x6 1100T(6x3,3) Sapphire HD6870 and 3,25mb RAM ('cause of 32bit(windows 7)

if you want send me a link to a couple of your textures and i'll have a quick look

Your problem is most likely the 32bit windows and lack of ram, which are sort of the same problem... I had similar trouble back when I had a store bought laptop.
