Decals causing Z-fighting

[Springheel]

I've noticed that sometimes that when I use decals that cut through models, I get z-fighting sparklies where they intersect. I'm not sure why this happens, as they are 'cutting' through each other at right angles, so nothing should be overlapping. Additionally, I've only noticed this with decals that I've made, not default D3 ones (yet).

 

Is there some specific keyword that is supposed to be used to keep this from happening? Anyone else noticed sparklies with decals?

In game it z-fights?

 

hmmm

Yes. It doesn't matter whether it is on a patch, or whether it is part of the actual model itself. I've created a pendulum on the grandfather clock by creating a flat square and putting an animated texture of a pendulum on it. It works pretty well, but the edges of the square (which are transparent) are causing sparklies where they intersect the side of the clock, even though it's at a right angle.

Check with r_showTris 1, if you have very long thin triangles, this can cause them sparklies.
