I had some success with DStudio ...
1.) In 3DC, export ...
- bump map.
- displacement map, zero level is black.
- Note the depth factor ... in my case it was 6.595.
2.) In DStudio ...
- import your mesh.
- load the bump map: strength 100%, neg=0, pos=0.20 ... but you have to play with that.
- load the displacement map: strength 100%, neg=0.6595 == 0.66, pos=0.66 ... but you have to play with that.
With these numbers, the model looks similar for me in 3DC and DStudio.
The only problem I have to solve is that I can see the UV boundaries in the renders.
