Extensions | Notes |
iff | The Nothing Real .iff format is not the
same as the Amiga format with the same extension, although they share
certain structural similarities. The NR .iff format is licensed to Alias/Wavefront
for use in their Maya product, which means Shake is ideally suited to
work with Maya. Since Shake deals with this format internally, you will
get the best performance by maintaining your intermediate images in this
format as well. It can be 8-, 16, or 32-bits per channel, as well as maintain
logarithmic information, alpha, and Z channels. Currently, not many packages
support this format explicitly, but if the package supports the old TDI
(.tdi) format, it will work with .iff as well, as, for example, is the
case with Interactive Effect's Amazon 3D Paint. There is also a free plugin for Photoshop and GIMP for .iff files. It can be found on Alias/Wavefront's site: http://www.aliaswavefront.com/assistant_online/entertain/maya/library/plug_ins/index.html |

Shake works with images bottomup, meaning 0,0 is at
the bottom left corner. The Cineon and Tif formats allow you to write
them either bottomup or topdown. Because of Shake's bottomup nature,
you will quadruple the I/O time (actual render time remains the same)
when dealing with topdown Cineon or Tif files. You can set which way
you want Shake to write the images - reading either way is no problem,
except for the speed hit. You place this in a .h file.
Add these lines to the include/nreal.h file, or in your own .h file in your startup Directory (see Customizing Shake for more information on setting up your own .h files). We recommend placing it in your own .h file, as the nreal.h file will get overwritten at the next release. script.cineonTopDown = 1; script.tiffTopDown = 1; You can also set environment variables in your .cshrc (or .tcshrc or whatever): setenv NR_CINEON_TOPDOWN setenv NR_TIFF_TOPDOWN Setting these variables forces Shake into topdown. mode. By default, Cineon and Tifs are set to the slower topdown.,
as there are many other software products which do not recognize a bottomup
image. If you write a bottomup and read it into another package and
it upside down in that package, you have four choices: |
jpeg, jpg jfif |
You can set the quality level in the FileOut, as well as determine
which channels are present in the file. |
.avi, .mov |
The QuickTime format is available on the NT only. Avi's are written
through QuickTime. If you select either as your output format, you have
3 additional options:
|
rgb, sgi, bw, raw, sgiraw | You have the option to set which channels are saved into the output file. |
rla, rpf | Adobe's After Effects and
AutoDesk's 3D Studio Max do not properly support the original
Wavefront specifications for the rla file concerning the Z channel. Therefore,
you have to explicitly write the image in a specific format, the rpf
(Rich Pixel Format) in the FileOut but use the .rla
file extension in the file name, or else these packages will not recognize
the extension. |
tif, tiff | Photoshop has a bug that
trashes 16-bit tif images if they are big endian (e.g., created on IRIX)
and read on a little endian machine (e.g. NT). We have added an environment
variable to write little endian images that will be read properly by Photoshop.
This only applies in the case of images written by IRIX and read on NT. setenv NR_LITTLEENDIAN_TIFF |
yuv,qnt, qtl, pal | You have the choice to write out in NTSC or PAL resolution, or 1920x1080 4:2:2 8-bit. |
