Question on FlagDecal quads

[NecroBones]

So I've searched around a bit, and looked at this thread and this one too.

I have the flag decal showing up on a fuel tank I'm working on, but what I did is add the decal mesh such that it is superimposed on the surface of the fuel tank's mesh. The decal works, but it's doing the Z-fighting thing, and flickering in and out in the center. What's best here? Move it out off the surface a little?

I don't want to replace polygons in the model's mesh, since transparency works on flag decals. So I'm just curious how people are applying them onto surfaces without it flickering through the other mesh.

just push it out from the surface a little bit.

OK cool. I was suspecting that's all people were doing. I'll give it a shot. Thanks

Does anyone know the minimum distance between the flagdecal and the model, so it doesn't z-fight?

[nli2work]

I do around 0.001; camera distance affects it too. The further out, the more space you need; but the flag decal is also smaller on screen so you can't really see the z-fight.

0.1mm (0.0001) is fine for me. No z-fight and no visible mesh difference. Works even with curved surfaces.
