I’ve been searching for a simple answer to adding water to my game for ages but I can’t seem to understand. I’ve tried using a flat blue egg model and then having it move with the character like the skybox does but I’m 100% certain this is completely the wrong way of doing it.
Also if it’s any help, I’m using perlin noise to make a heightfield map and then was planning to have the water fill in the lowpoints. Is this achievable?
Can anyone shed some light for me? Sorry if it’s a pretty dumb question
Oh so it is the right way to do it. I thought there was something wrong because I seem to get this problem that where the water plane touches the terrain model, it starts flashing and flickering when I move the camera. It’s usually on areas where the water plane just overlaps the ‘sand’ part of my terrain. Is this meant to happen?
My terrain is generated when the player moves to the edge of the area so I thought it best to have the water move with him or else they will get to the end of it eventually.
Thanks for the help, I’m having a look at the Yarr source now
Setting the “far” value to something smaller than the default might resolve some of the z-fighting in your case (but not too small as objects start disappearing once they are further “far” units from the camera). Changing cam len settings might help but this can be a tricky problem to deal with which might require a shader to totally fix.
Ah thanks cslos, that’s sorted that problem, the near attribute of my camera lens was 0.1 when the default is 1.0, there’s only a tiny bit of flickering when the player looks at the water in the distance but it’s ok for now. Plus the flickering kind of looks like waves or ripples or something.
Thanks for the help!
I’m not sure if I should start a new topic for this, but I was having another problem with the seams between the terrain chunks. I have the texture generate from the perlin noise but where grass connects with sand, and sand with water etc, there is a line of sand in the middle of grass or a line of blue (water) in the middle of sand etc. I have borderStitching on and that’s made things look a lot better but there is still this problem. There’s a picture of it attached.
