Hello
I'm using Stitcher Unlimited 5.6.2.  on a Mac Pro, running mac os 10.4.10.
 
I'm importing HDR pictures which came from PS and also from a Testversion of Photomatix. Both in .hdr format.
Everything works fine during stitching.  
Now, as I want to output the final Panorama again as HDR. nothing happens. I tried the external blending with enblend3 as well as smartblending. Outputing an TIF file with this two methods works fine.  
 
Does anybody know if there any problems in outputing an HDR file?  
How can i render an HDR file in any way?
I want to to the Tone mapping in PS or Photomatix.
 
Thank you
andy

You might have a problem with the final picture's size. I have found out that HDR output larger then 4k*2K pixels never works, 2K*1K works. In TIF everything is fine. Realviz already acknowledged the problem...  
You might also be running out of memory, both processings like 2GB allocated for stitcher.

what i found out: everything works fine if i use .exr file format.....
so. simply switch do exr an thats it

I've been having a similar problem but more to do with output being black and blank!!
 
I can stitch the .hdr's or .exr's fine and can output any size using Linear or Morph blending, which gives a file that previews black in Photomatix, but tonemaps fine and shows detial in the preview window.  
Everytime though, i try and use Smart i just get a black empty file with no data in. If i use Enblend no file is created.
 
I'm trying this on a G5 powermac Dual 2.3 with 5.5gb of ram and latest version of osx and stitcher.
 
Realviz arent forthcoming with a solution!!
