Displacement map help! Going insane...

looks fine to me...

Hi oglu,

well, it's kind of extreme. I'm getting maps like this both at work and at home. They don't displace correctly at all. I must be doing something wrong along the way but I can't figure it out.

Just wondering if anyone else has had this. I have had it work correectly for me before, but now I just can't get it right :(

Here's a max render of the disp map.

subD a sphere up to 1mio in mudbox...
go to map --> sculpt model using dispmap and use your .exr to displace...
if this is looking fine something is wrong with your rendersettings...
maybe your render cant read 32bit files...

[DrZenith]

Yeah, it's different/better but still Fubar. I don't get it. And my renderers are mr and vray.

Hmmmmmm....

in this case your search distance is to low...

[DrZenith]

Ahh ok... I usually use the best guess button, is this not recommended? Technically should I be able to set the search distance to say...500? and it would be ok!?

Thanks for the help on this one :)

Actually one more thing, as you may notice, the displacement map has a slight wireframe in it....Why is this?

You may want to use this tutorial to bake your disp map...
