Conclusion: Use .tif for greyscale texture images as opposed to .pic of same
pixel size, since .pic is uncompressed at render time.
Thanks.

I believed XSI renders compressed tifs. Or else all the tif files would be 1
.4 megs each.
I am remembering that I convert pics to tifs in XSI and the editting
software didn't like
it because they were compressed, I had to run it through Photoshop to make it
work.

That's interesting. In my experience, pics are always smaller than tiffs,
unless you're using lzw compression on the tiffs, which I don't think XSI
can use. A regular Tiff has no compression at all, whereas pics do contain
lossless compression automatically. Just save a solid white frame from
photoshop in the two formats and compare the file sizes!!
Between the two, I'd always use pic, but unless you're having problems, I
wouldn't worry too much.

Subject: .tif vrs .pic
When using greyscale image for texturing, I have a choice of .tif or a
desaturated .pic. Granted that the image pixel sizes are the same, the
greyscale .tif has a smaller file size, but I understand that
XSI/Softimage will have an "easier" time with the .pic as it is
compressable and etc. If render memory space was an issue, what format
would you use? I understand .map files and will not be going that
route.
