    OK, I had opened a thread for Dallas, and had started posting things on there, but with my other track (and #1 priority for the last few months): Phoenix Street Circuit F1 Grand Prix from all 3 years (so 3 different versions) 1989 - 1990 - 1991.

    I'll be posting progress here so that people don't think that I just opened a thread on Dallas and see nothing more (since I'm not concentrated on that for now) except on progress of other tracks.

    So for now, here is the video I posted on the other thread, this time it's in the proper one ;)

    Last night did some work on the walkbridges... I have some weird shading issues for the sponsors: sometimes they flicker or they have some strange effect to them. Any suggestions ?

    I assume sponsors are a separate plane, on top of the actual model ?
    In which case, increase distance between model and the plane. Or make a cutout on the bridge model, the size of the sponsor (delete or reverse normals of cutout so that it's "filled" when looking from inside the bridge).

    And if they are separate planes try disabling shadow casting.

    Could be a combination of all suggestions above...

    ...and I increased the distances between the model and the plane... and still (depending on which side we're looking at it) still gives me the wacky issue:

    By the way luchian, I followed your tutorial for the real shading settings and maps for the tamac, this is the result I get, it's ok, but I think it can be way better from the examples you showed :(

    It will be in the shader attributes dropdown list in KS editor. I tried this out after Lilski posted that info.
    An example of that is in ksPerPixelMultiMap_AT_NM_Detail. Not saying thats the shader to use, just using an example, but I used that to play around with shadowBiasMulti, and it started removing the self shadow from my Armco mesh for example. I haven't used it or explored that any further, but that's the gist of it, I think.

    I was merely the scribe, Lilski provided all the knowledge :). All the textures are important, including the alpha in the diffuse. In your case, maybe the issue is with the detail not tiling too seamlessly ? Or with the multiplication numbers in the shader ? Don't really know just by looking at the images.

    Yes, this seems to be the solution I needed. I just need to confirm tonight that this was the real problem. Can't wait to try it out :)

    GRRR... still flickering. Now it's just one on the main straight, all the other sponsor ads seem fine.

    However the shadowbias trick really helped my concrete walls look way better :)

    Difficult to say by not seeing the mesh model. If the billboard is two sided:
    Maybe one side is not flipped correctly.
    Or the normals are not facing in the right direction.
    Or the corner vertices are wrong merged together.

    The billboard is one-sided, the support of the billboard is 2-sided but merged into 1 mesh.
    For some reason, I'm almost thinking it's a lighting issue depending on the light source and the way it hits the billboard, have you heard of such an issue before ?

    Really looking forward to a release! Lots of nostalgia from F1GP on my Amiga back in the day, if you need a tester of sorts, I'll be only too happy to help! :whistle::)

    You'll have to wait a while before any release, there are 3 version years to do, all 3 have different configurations with the biggest one being between 90 and 91. :)
