Weird vertical lines on terrain

Recently (a week or two ago) I started seeing thin vertical lines in the distance in my terrain. We suspect they are related to the trees placed in the terrain editor. But when I approach them, they disappear. (the image here shows several of them; if I take another step forward, they disappear.) Does anyone know what’s going on with these? This happens with 2.0 and 2.01.

thanks

Still very new to Unity, but this process alone has helped me much.

It looks like one black pixel on the edge of the render texture, or one that is only visible when filtering is applied. Maybe there is a bug with the billboard render texture generation. We’ll see what someone from ut says.

And TAD: that seems completely unrelated, but that treatment is so good its nice you mention it :slight_smile:

I also see the tree billboard corrupt. I reported this on the alpha list (seemed to only happen with the Chinese tree (forget the name, Chinese Elm maybe) in the editor, but I guess no one else was seeing the problem.

I have very low framerate on the island demo, and my system has no FBO support becasue of OS version (Aras knows)

Vid card: nVidia GeForce 5200FX

I didn’t report further on it because I figured it was my crappy card + OS version (10.4)

Perhaps it’s related. I have attached a screen of the island demo.

Does this happen with every type of tree? I can’t quite tell from the screenshot since you have a couple types grouped there. There is a “problem” with Detail meshes rendering lines at the billboard borders if any of your textures aren’t transparent along the edges (this has to do with the way Unity combines all Detail mesh textures into one texture sheet). But trees work in a different way so it’s a mystery to me why you’re getting these lines.

I have a folder full of whacky glitch screenshots like this while working on the island demo using the alpha version. They’re quite pretty actually :wink: but I think they had to do with the glow effect mostly.

BTW, I’ll race you to the 1000 posts mark on this forum :wink:

Hey man,
This screenshot is from the final actually, and built with Unity inide. Heh, odd. We should state a collage.

Ah! It will be a close one indeed! Any bets people? :wink:

Take care,

Yes, it is happening with just two of my trees. Is there a way I can check/fix if it’s a lack of transparency along the edge of the combined texture?

So I’ve tried different filter settings, and both Repeat and Clamping the texture, and still no luck. The lines flicker on and off on both the left and right sides of the billboard tree, even showing up in Scene mode. It’s happening with the Sycamore that came with 2.0 as well as one of my other trees. I’m getting desperate–anyone got any tips?

TIA,
Dave

I’ve also just come across this with the built in tree’s. (from the terrain demo package)
