Hey everyone,
I have fnished modeling my model in Zbrush, I followed all the steps
from the Pixalogic Zbrush to XSi intergation, and yet, my Displacement resault
is similar to the orignal, but many many Detail is lost in the procces.. any Idea why?

The steps I followed:

1.Model in XSI
2. UV in XSI
3. Import, Check UV ..etc
4. finish sculpting
5. Create Displacement map, Dsbpix - 2, Smooth UV, 4096X4096.
6. Export, as a 16bit Tif
7. Import to XSI setting on View dependet, and Depth factor just like I took from Zbrush

now, There are no artifacts.. and so on, but a Whole lot of detail is lost.. only big Massive defomrer areas Are visible and working.

any Idea what would cause this? Thank you all very much.

these are my results:

What are your GeoApprox settings?

Try setting it to Fine then use these settings as a starting point.

max displ: = to your alpha depth factor
length: 2
view dependant: on
min: 2
max: 7

You might think that 7 for max is high but whats happening is that the length param is stopping it before it gets that high. Then if you require more fine detail, lower the length to 1. Typically you won't have to go below .5 which means anything smaller than a half pixel won't get subdivided again.
