    Hi everyone

    The problem that I have is that the “underground” shines through the rails of the construction placed on it. This happens when the distance of the camera is big enough. The “shining through” appears like a kind of flickering. If the distance of the camera is small, everything is displayed correctly. Do you have any idea how I can solve this issue?

    It’s Z-fighting, this small gray things too close to ground place, you need to lift it up a little bit.

    Hi Mikhail

    it’s true, if you increase the distance between the ground and the rails, the flickering disappears – but the distance must actually be very large, so that it becomes obvious that the construction is no longer on the ground. the other objects of the construction also lie on top of each other, wirhout that something flickers. is there no other solution? Rendering order doesn’t help, right?

    Thx for yout quick answer

    Hi,

    You can also make your camera volume smaller by moving the far and near planes closer to each other. If you have distant objects than the near plane can be something like 1 unit or more. This should help use the depth buffer more effectively.

    Hi Yuri

    thank you both for your quick help. I just don’t understand, what you mean by “moving far and near planes” – what exactly do you mean in terms of the camera settings? Just I manipulate lens settings – like reducing the focal length to get closer to the objects and also the verge3d settings “Max Distance”. Please get me some closer to where to find these settings? Thx

    these settings are called clip start and end:

    Yuri means Start and End Clipping of the camera. Try to narrow down them as much as possible to your scene.

    Yes okay – I try to find the best settings for camera clipping. I wouldn’t have thought that the clipping of the camera was connected to this. Since I come very close to individual objects in some predetermined camera positions, I have to test whether 1 Unite is not too big. I try it out. Many thanks for the tips.

    Jo – the problem has been solved. Many, many thanks. Clipping was the right parameter…

    best so
