Weird lines in render

juguefre

Hello.

I get this weird black lines in the far of the render in UDK and also when I do render in maya, but it doesn't show in the maya viewport.

I overlaped almost all the faces on top of each other using a mel script, can this be the problem?

thanks in advance for any help.

That ground plane, is that one mesh or is it split up into small squares?

Is this texture padded? Have you coloured the space between UV islands to make sure it mipmaps nicely?

Here, this pics might answer your questions, JamesWild I think I did because it is showing the texture ok at close distance but is really bad if look far away. (sorry for my english)

Fill the black space around your UV islands with colour - when viewed at a distance a lower res version of the same texture is used to prevent fuzzy, noisy, flickering artifacts due to there being too much detail to represent, but as a result the texels are bigger and bleed out of the polygon.

Here's an example:


The image will be reduced probably 8/16x in most circumstances, so if we reduce the image without colouring the padding and overlay the unwrap:

You can see that the padding has bled into the island, creating the seams you see.

No problem, good luck with your project!
