I don't see your point  when you say 16 tiff are broken
Because i have just rendered over 2500 x 6  frames in 2K in tiff 16.

But i ve noticed in fusion that the pixel aspect is screwed by default. I fixed that by entering myself the right pixel aspect.

16Bit Tiffs are definitely broken in 5 (and 5.01).
I currently try to render an image that was fine in 4.2, but the output from 5 can't be opened by Photoshop (6 and CS) or standard After Effects (5.5 and 6.5).
DFX+ can open it, but loads it 20 pixels high and very looooooooooooong with an absurd pixel aspect instead of 3300x2460.


The only loader I've found so far who can open that stuff is SuperTiff for After Effects:

Now I convert each image with AE to something readable by Photoshop first...

I also got weird results from OpenEXR 32bit - a red background was suddenly black when opened with the Photoshop plugin.

If anyone knows a working 16/32bit format in XSI 5 that works with Photoshop I would be thankful.

BTW. Those image formats really need an overhaul - I miss Multilayer PSD, RLA and especially RPF from Lightwave...

Cheers,

Thomas

Hi All,

Anyone else have a problem when you are rendering 16bit SGI or TIFF
files? I get unfinished tiles in my images when I use 16bit (HD
1920x1080), however switching to 8bit solves the problem. And there is
no error in the Log files that I can see.

This is with: XSI 5.0.1 32bit, Windows XP sp2, 2GB Ram, Dual Opteron.
