Bad math in the Lava Shader?

[Forboding Angel]

Why is there a giant seam in the middle yet it's seamless everywhere else?



Shader is taken from violence 4.2. I've modified it slightly just to make it draw underneath water instead of on top of it.

I've tried it with texture sizes 1024 and 512, neither have any effect.

Fixed it. Line 263 should be:

Code: Select all

DrawGroundHuggingSquare(1,1,1,1,  -4*Game.mapX*256, -4*Game.mapY*256,  5*Game.mapX*256, 5*Game.mapY*256 ,SYNCED.lavaLevel) --***map.width bla

Gah, that just shifts the seam actually.
