cool, thanks
Wasn't sure why that number was used but if 45deg. was the target fov with default settings and 50mm I can understand that.

Where'd 41.4214 come from?
If aperture is camx width in mm then I’m totally confused about where 41.4214 comes from??
Any ideas?
Thanks much,

If you use “set path” in tcsh, then you can use spaces. But if you echo $PATH, isn't it concantenated using semi-colons?
hmmm, mine doesn't concatentate. Also our current tcsh used either spaces or simi colons.

Ah, that makes sense now. I don't think it was ever intended to allow spaces as the separator between paths. In H8, it was fixed so that one could have spaces in their paths (eg. CProgram Files). So this broke your incorrect (but previously tolerated) HOUDINI_PATH.
My tsch requires spaces for it's path so I used that convention.

How does adding semicolons help with the space in HOUDINI_PATH issue?
using hconfig -ap I noticed that the example paths were seperated by ;'s
My tcsh seperates paths with spaces
Houdini7 worked with the spaces seperating path entries
Houdini8 doesn't like the spaces
Replacing the spaces with ;'s fixed it.
new path:
setenv HOUDINI_PATH “.;${HIP};${HOME}/houdini${HOUDINI_MAJOR_RELEASE}.${HOUDINI_MINOR_RELEASE};${HSITE}/houdini${HOUDINI_MAJOR_RELEASE}.${HOUDINI_MINOR_RELEASE};${HFS}/houdini;${HFS}/bin”
old path had spaces
or more easily readable new:
setenv HOUDINI_PATH “.;$HIP;$HOME/houdini8.0;$HSITE/houdini8.0;$HFS/houdini;$HFS/bin”
old
setenv HOUDINI_PATH “. $HIP $HOME/houdini8.0 $HSITE/houdini8.0 $HFS/houdini $HFS/bin”
Does that make sense?

It turns out it wasn't adding HFS/bin that fixed it
It looks like Houdini8.0's paths no longer accept spaces
Houdini7.0 and before did.
so when I added semicolons it fixed it
getting houdini8.0 up and having help did it for me because I could search on path and see that hconfig -ap was the command I needed to figure things out.
Very cool, thanks all.

$HFS/bin and $HFS/houdini are included in it.
$HSF/bin is missing in my HOUDINI_PATH
I've never had a problem in Houdini 6-7 with my path.
I'll add $HSF/bin and see how it goes, thanks.
I'll also see if it was being set anywhere else.
Thanks again,

I'm having a problem with setting up houdini 8 to work with our environment variables.
It seems houdini 8 breaks when it encounters the HOUDINI_PATH variable.
If the variable is even created and empty it crashes out houdini 8.
With Houdini 7 it works fine.
I'm just installing 8 now to test it out in our environment. Any ideas?
thanks,

What is this cygpath used for in the houdini_setup file?
What is under this path?
I've never heard of this and it looks like it's setting HFS near there if it exists??
This blows up on our windows machines. I'm thinking that our version of tcsh doesn't like the -f in the if statement?
Any way it's messing up on the if statement in this area.
-mikey
P.S. Looks like cygpath is use for linux??
Is there something missing from in front of the -f??
#
# Check for cygpath
#
set CYGPATH=`which cygpath`
if ( -f $CYGPATH ) then
set heredos=`bin/hpwd`
set here=`cygpath $heredos`
setenv HFS $here
else
set here=`bin/hpwd`
setenv HFS $here
endif

It looks like the problem is with UVproject. UVtexture works great!
Is this a known bug with UVproject??
Say your using a tube with 5 divisions, the 5th division becomes the entire seam with UVproject. Higher divisions are harder to notice the seam but it's always as big as the last division.

cylindrical mapping seams on polygon models
I’m not very experienced at cylindrical mapping. I’m getting large seams on my polygon rockets I’ve modeled.
I can’t find a way to get rid of the problem. Can anyone explain what is causing the problem and what might be a solution??
Thanks,

Okay I used vorigin and a point sop to get the surface's normals to point at the light. Now the camera off angle renders the texturemap colors pure even if the light isn't oriented flat with the object and the camera is off angle.

Okay correction, it seems to work if the light and the surface's normal are lined up if the camera moves in this case it works. When the light and the surface normal aren't lined up the image gets darker.

Hmmm, it seems to only work if the camera and the light are lined up. As you move the camera off angel you get a darker render, not pure what the texture projected.

We changed Ci to Cf and are getting some results. I have to test this out but it looks promising. I think it's doing what I was asking for.
