Diss maps from 2 groups have different intensities?

[system]

Hello.

I’ve been trying out Zbrush 3.5 R3, but i have a problem.

I create a model (character), which has different UV spaces (a procedure I’ve been using for a long time in Zbrush 3.1). Export it to Zbrush, sculpt smoething in HD on the seam of the 2 groups (created by uvgroups), go to the lowest subdivision, leave only the head visible, and generate a diss map.
Then i hide the head, and leave the body and generate a diss map for the body.
I tried using these maps in 3ds max 2010 as bump maps, with the same intensity but as you can see in the attached image they don’t have the same intensity. The problem gets worse if i sculpt on some other parts of the body and the head.

Anyone knows why is this happening?

Shouldn’t the 2 diss maps have the same intensity (height)?

Thanks in advance.

Anyone???

If anyone wan’t to recreate the problem, just create an object (sphere or something), apply UVs in your 3D application, but Place the UVs of (lets say the half top part of the sphere) in UV space 0.1, and the rest at the space beside it.
export it, import it to Zbrush, create UV groups and sculpt something at the UV seam (the problem gets more intense if you also sculpt various detail with deferent intensities on each group).
Go to the lowest level, import your original model, re Group based on UVs, ctr + shift click on the top part to hide the lower part of the sphere, and create a diss map.
Repeat the same process for the lower poart of the object.
In your favorite application if you use these maps as dissplacement or bump maps with the same intensity you will see that the resulting bump or displacement intensity is not the same (at least that’s what happens to me).

Thanks in advance

After a few tests i noticed that the seam is visible if the diss maps are used as bump maps.
Anyone knows why is this happening?
