Strange rendered lines

Hi

I’m getting some very odd lines that appear to be connecting objects in our new game. This only happens on specific systems and unfortunately on all of our PCs and Macs these don’t appear, but I have been sent images a video footage by our client. They have seen these lines on 3 systems - 2 with Radeon x1600 with 256 VRAM cards and one with Intel Q965/Q963.

A little bit of the video is @ http://kinelco.com/dnb4lines/

They appear as though there’s some connection between the player and AI bikes. However, they are not attached or parented in any way in the project and no components have any connections. I’m not raycasting or using Debug.DrawLine or Debug.DrawRay at any point between the bike and opponents. As far as I can tell (and i’ve been through the project numerous times) there is no object, component or code that could create these lines.

I’ve a feeling its’ gonna be somethin really dumb n obvious but it’s got me beat!

Any ideas much appreciated!

Cheers
Paul

This could be a weird shader/video card/driver combination problem. Submit your project to us if you can in a Bug Report, and we’ll see if we can reproduce fix it. Use Help->Report a Problem

set the track surface so that it does not cast a shadow.

Thanks for the tip but the track surface is already set to not cast a shadow. I’m interested to know what your thinking behind the suggestion was though.

I will clean up the project and submit it to Unity shortly.
