Currently creating the Siskiyou Route. Myself and my partner Mike out in Michigan have noticed that when we run the route on OpenRails, the tops of our trees have the edges of the texture showing up as fine black lines... Looks like floating Xs above the trees. I've tried to verify that the problem is not unique to us. The entire top area of the texture is transparent in Photoshop. Trees are like most... 2 or 3 intersecting planes with textures applied. Vertices were combined so that the "box" was reduced to a double-sided 4 vertices shape with textures on both sides. Need more info? Drop me a note.

This is not a bug in Open Rails. This is an affect of antialiasing and a short-sighted design of the texture.

You can correct this behavior by editing the texture's alpha channel. You can also try to mitigate it by reducing the antialiasing effect imposed on the game by your video drivers.

Thank you for taking the time to answer my inquiry.

I looked at and tried to use the links you showed, however, following their ideas has not solved the problem.

I'm trying to understand what you meant by, "This is an affect of anti-aliasing and a short-sighted design of the texture.

What does "a short-sighted design of the texture." mean?

Thanks, D. Rickert
