32-bit .TIF Displacement Maps Exported w\ LZW Compression?

#1

When I try to render an object in Maya with a 32-bit .tif displacement map (RGBA, not B+W) extracted out of Mudbox 09’ I get the following error:

// Error: (mental ray) : …displacement_normal_test/sourceImages/slimeBall32Disp_v3.tif: file format subtype or version not supported //

If I try to convert that same .tif to a .map with imf_copy, I also get a similar error (unrecognized file type).

If I take that .tif into photoshop and save it back out with no LZW compression, Mental Ray renders it just fine.

Is there a hidden option somewhere to turn off LZW compression by default?

yes i have the same thing doing 32 bit tiff in modo and setting them up in XSI,
with mental ray.

on the wiki of xsi say is a notification more than a warning but nothing else.

think the best way is to use EXR files…
