Ok, I've been trying different settings to overcome this problem but I haven't had any luck. I have this model and I made the displacements in mudbox. Everything works fine in mudbox, no problems at all.

However, when I export the map, I get some weird white spots.

And that is causing (I think) some weird problems on my displacement

Ok, I assume that exploding face has something to do with the white spots, because they are where the exploding occurs. However, for the life of me I can't seem to find a way to get rid of them :-/

these dots can have different reasons...
there is not enough geometry in the lowpoly...
the search distance is not correct...
and some funky problems... :)

go and open the dispmap in photoshop and overpaint the dots will help...
a dispmap is only a picture you can paint in whatever you want... :)

well, I got it to work, thanks. It turned out it was the ray distance thing. I tried a smaller, but not so small value and the white spots began to go away. I reached a point where they were just gone so everything works fine now.

On a side note, is it just me or Maya displaces the model too much? I am finding myself in the need to decrease the alpha gain on my displacement texture because the default setting displaces the model way too much :-/

:cry:
