Blank 32bit displacement maps from 3.5R2 ?

[mattock]

Hi, When i create a 32bit displacement map its coming out completely blank and grey?.. 16 bit works fine. Ive selected 32bit, and adaptive.

If i create the map from subDivision level 1 i get a very very faint image… but any higher and its completely blank… what level should i be creating these from ?

Also when i try and import this file into maya it says its an unsupported format ? even though i have 32bit tiff plugin enabled.
:o
any ideas what im doing wrong ?
many thanks

R2 is no longer supported. Please update to R3. If you did not receive your update email last week, you can submit a Support ticket in the Upgrade category at http://support.pixologic.com

Thanks, I tried on another machine with R3 in my college and still get the same problem, a grey blank 32 bit displacement ?
