So, our game was recently released and we’re now doing maintenance and bug fixing based on feedback.
One issue we’re dealing with is major z-fighting happening on EVO 4g that isn’t happening on other devices.
Is there something on our side that we can do to fix that or is it beyond our control?
in 3.4 you will be able to tweak depth precision - so stay tuned
I don’t know if this is aplicable to unity, but i had same problem with a OpenGl project, and i solved it redefining Z-near and Z-far frustrum atributes.
I’m not sure if this could work in Unity, but try to scale your whole game (scene, objects, everything) to make it bigger, then you’d have more Z-depth precision.
Here a little draw i’ve done to explain this beter:
Sorry for my bad english (and my bad drawing, lol).
it also holds in unity.
The max z precision the hardware has can be expressed as a value x = far clip / near clip which must be below a given value. for mobiles its somewhere between 100 and 10000 depending on hardware (there are weak androids where it really is on the bottom end there), for desktop its 30’000 to 50’000.
another important thing is to remain within the range of the 0,0,0 point, don’t go too far off from it (normally not more than the value above can reach) or you get z fight and jittery rotated objects and alike
