Possible New Bug With HDRI?...Please Help... 2004-04-20 - By ccoles_avengers

Hi All,
After being inspired by Todd's physics animation clip, I decided to
try out doing some HDRI scenes, which I haven't done in a long time.
But much to my dismay, when I tried using the HDRI lighting scheme, I
noticed some serious problems. Bascially, most of my channel
information was gone on many of my textures (although in the shader
room, the channel information shows up just fine). And just to note,
under "regular" lighting, these objects look fine.
I decided to test this out on other objects that I had previous
success with using HDRI lighting, but the same problem occurred. I
even noticed that some colors were completely *changed*, whereas when
I turned HDRI off and used a conventional spot light, the colors were
back to normal.
I then decided to do a test and used simple sphere primitives and all
CS3 "preset" textures and noticed the same problem: for some textures
HDRI lighting worked and for others, the spheres looked basically like
silhouettes. Even changing HDRI maps didn't make a difference.

I have recently installed Poser 5 and Transposer. Could these
installs have caused some problem with CS3's functionality?
This is a really big problem for me since it seems that my previous
HDRI work, though few, is now affected, besides the fact that I
definitely can't go forward in doing HDRI work until this issue is
resolved. Any help would be greatly appreciated.
Also, here is the link to my test HDRI CAR file. I have also provided
a link to the HDRI map file (zipped) I have been using as well.
