[Plib-devel] texture repeating

[Curtis L. O. <cu...@me...>]

Steve,

In ssg is there a way to control whether a texture is set to "repeat"
or not?

As I start working on runways I'm starting to notice some artifacts.

I want to slap a texture down on top of a specific area and have the
texture cover it completely ... texture coordinates of lower corner
are (0,0), upper corner are (1,1), etc.

Now, what I'm finding is that if I have a texture that is all black
along one edge and all white along the other edge, I get some bleed
across to the opposite edge ... i.e. some of that white on one edge
scrolls around and shows up on the opposite edge and visa versa for
the black ... this makes it really ugly to piece together adjacent
textures because you always can see the joint because of this bleed
across.

I'm assuming this is because the ssg textures are by default set to
repeat, right?

Do you have any strategies you can share for avoiding this problem?

Thanks,

Curt.
