Quote - I tried 32-bit tiff as displ. map and it gave "bad file error".  didn't try exr.

 

16 bit tiff would be the tiff format we support at the moment. I believe EXR is supported as an image format but we don't support (to my knowledge anyway) vector displacement. So if you're goal is to use an EXR to that end, you probably won't get the result you're expecting. Admittedly, my tests in this regard have been few, finding 16 bit tiff displacement to be sufficient for most Poser needs.
