Artefacts when using displacement with AUV

Hello, my problem appears when i’m trying to done a displacement in maya with a displacement map generated by zb, using AUV mapping.
The size of the map, seams to modify the problem, but it always here…

With a 2500*2500 map :

With a 4096*4096 map :

Have you an idea to fix this ?

ps: I can’t import a lowpoly with new UV unwrapped by hand cause zb is craching…

ps2: sorry for my bad english.

First, 2500 is a poor size for a map. For best results, your textures should always be a power of 2 in size. Such as 1024, 2048 or 4096. Assign a blank texture to the model that is the size you’re going to want to use. Then press the GUVTiles button to assign the mapping. That makes sure that the mapping is ideal for the texture size that you’re using.

Also, are you remembering to flip the texture vertically before exporting it from ZBrush?
