Z-Test with moving camera

Michael_Schneider · July 25, 2020, 9:51pm

Hello,

i am drawing in screen space and ingame and get a weird behaviour.

using (Draw.ingame.InScreenSpace(Camera.main))
{
    Draw.ingame.WireRectangle(new Rect(10, 10, 100, 100), Color.black);
}

First everything is ok. See the rectangle bottom left.

But if i move the camera in z direction i get a rectangle which opacity is reduced.

Am i doing something wrong?

Kind regards,
Michael

Hi

Are you using a render pipeline?

Hi,

Yes i am using URP.
I did also a trst with the default pipline and there its working.
A minimum test with a fresh URP project shows the errror.

Upgrading the shader reduced the problems but did not made it go away.
Moving the camer to z > 1000 from 0 does show the problem in my test.

Ok. I think this bug will be resolved in version 1.2.3 which will be available on the assetstore in a few days.

Really nice,
Thanks for your work.

The fix works like a charm.

After some testing one littel thing caught my eye.

Is this the reduced opacity described in the features or should it be invisible?

That’s the reduced opacity. Behind objects the lines reduce their opacity, but are still faintly visible to aid debugging and other things.
