Elliptical filtering 2005-05-31 - By Bernard Lebel

Hi,
I am baffled at something. I have a scene with rather large textures
(3500x3500 and higher). In Pic format, it renders in 45 seconds.
So I'm looking to save render time, and memory while we're at it, so I
convert textures to pyramidal map float files (imf_copy -p [...] map
rgba_fp).
Then I turn on elliptical filtering, set the Maximum Pixels for Minimum
Radius to a low value 1.3, because higher than that is generally not
necessary.
In the past, I got much faster render times. However right now the
render time explodes: it's at least 5 times longer than with the Pic
version.
Any idea?
Thanks
Bernard
