Weird splitting in displacement map from mudbox

Macattackk

Im making a displacement map in mudbox for terrain to be used in world machine. Everything is fine except theres a row of pixel artifacts in the middle which is non existent in my model. any reason why this may be happening?

oglu

are your uvs using 100% uv space.?
mudbox dont like that...

Macattackk

so you mean shrink the UV's so that they are not at the borders of the 0 to 1 space?

oglu

yes...

Macattackk

that fixed it BUT, since the UVs are no longer at the borders of the 0 to 1 space, the displacement map is shrunken down from the borders of my 2048 image and i need it to be 2048 to be mathematically correct in world machine
