I want to make a weapon that can freeze terrain and make it slippery. To do this I instantiate thin, flat cylinders with an ice texture and a slippery physics material. I am instantiating it slightly above the terrain itself (around 0.01 units above the terrain). The problem is that you can’t see the ice a lot of the time, and when you can, it flickers a lot.
How would I fix the z fighting?
You can’t ‘fix’ the z-fighting, if the sheets are all at the same height the graphics card won’t know what to draw and in what order.
You will need an offset for each sheet.
So for each sheet you instantiate simply increment its height by 0.01 units or whatever stops the z-fighting.
You might want to try projecting it onto the terrain using a projector. Using a 3D cylinder you might need to increase the offset a little bit more than 0.01.
