User Textures Flickering When In Front Of Walls

[Kydoimos 916]

I've noticed that when using User Textures they flicker at a distance if you place them closely in front of walls (e.g. impro posters, etc.). Is this just a problem with the Alpha and Beta? I updated my drivers and didn't notice any difference.

This is how engine renders two polygons really close to each other. Try to move user texture a bit farther.

ah, that's a problem :) I'm trying to make it seem that the texture is attached to the wall. Any suggestions? My one work around is using fog to mask the draw distance. I have a massive Coca-Cola billboard (10m user texture) placed very, very close to the wall of a building so you cannot see the edges. I don't know how to do any of the modelling lark, otherwise I'd just create a think enough base or frame and use the attachto command (which I assume would work?).

Any ideas?

You can get away with something further from the wall than you think. You also might try playing with the z priority of the faces by selecting your billboard and going to

faces/move to top or move to bottom and seeing if that makes a difference.

Unfortunately, the z buffer, the thing used to calculate the draw order based on distance, uses a ratio that gets less accurate the further you get away. Usually, the buffer is more than adequate to accommodate the range of distances seen in games but this game has a very wide range. The result is this 'z-fighting' artifact you're seeing there, as the renderer can't really tell which thing to render first, it's rendering bits and pieces of each per pixel per frame.

I got really sneaky in the end. Put shoot house walls (crouching, prone, standing) behind the user texture which stopped the flickering. Not only that, but it looks like a real billboard now! Thanks for your help though,
