Thanks John,
Over a year and a half later… and you helped me out with a new install again.
Cheers!

Thanks for the feedback.
Received mine today… a much humbler configuration though.
Intel P8400
2 GB Ram (Plan to add more)
Nvidia Quadro 2700M 512 GB RAM
(Am replacing a 6 year-old desktop workstation… so it should still be an impressive upgrade for me)
I've been lurking around the M6400 owners forum and there seems to be a lot of stability issues cropping up. You've had yours running Vista/Houdini for almost a week now… have you encountered any problems since your previous post?

Am finally upgrading to some new hardware and have a few general houdini/linux/networking questions. Apologies in advance if I missed these answers elsewhere.
- Can ifds generated on a machine running a 64-bit version of OS/Houdini be rendered on a machine running a 32-bit version of OS/Houdini? (Assuming amount of memory is not an issue).
- Are there any reasons to avoid mixing 32 & 64 bit OS/Houdini systems in a networked production environment?
- Do you HAVE to install a 64-bit OS on 64-bit capable machine?
- Do you HAVE to install a 64-bit Houdini on a 64-bit capable machine?
Thanks

Looks like it was a problem with h9.5.190 on linux… found a mention of this in the journals.
Upgraded to new version and it's working now.

Houdini 9.5.190 on Linux
I've been trying to replicate the results in the “Rendering Voxels” segment in the “Introduction to Fluid Dynamics” tutorials and am having some dificulties.
Following the tutorial steps I get…
http://www.afcg.com/sesi_forum/smok_test_1.jpg [afcg.com]
Teapot on grid after adding the IsoOffset Sop with the output type set to “Fog Volume”.
http://www.afcg.com/sesi_forum/smok_test_2.jpg [afcg.com]
First render before applying any materials.
http://www.afcg.com/sesi_forum/smok_test_3.jpg [afcg.com]
Second render after applying the “billowy_smoke” volume material with settings as indicated in the tutorial.
From these images… is there something obviously wrong?
Any known bugs?
System issues?
Thank you for any input.
Attached hip file made from default houdini & following the short steps in the tutorial.

Will try this one again…
I know it was always considered an unsophisticated way to add “reflections” to an object, but…
… how do you replicate the simple specular reflection map light that was available in pre 9.x releases?
Thanks.

Thanks Mark,
I just multiplied the Of by Alpha and it now works fine.
Strange though… I'm keeping Alpha as a float when multiplying with Cf and Opacity. When I converted Alpha to a vector before multiplying I got strange results.
Lot's to learn.

Why do so many answers lead to new questions?
Here's a simplified example of my new problem…
A scene with dozens of spheres… many of them overlapping. I'm animating the Alpha of each sphere using a random function in a point SOP. Everything works fine and the spheres dissolve on at random times.
The problem is that foreground spheres that have not yet dissolved on are acting like matte objects, cutting away the spheres behind them.
I don't have this problem when using the supplied Super Material shader… only with one of the newer supplied VOP shaders that I modified to recognize point Alpha.
Any additional pointers?
It would be nice to have a VOP example of the Super Material shader.
Thank you.

Damn, that was easy. (Well, with detailed instructions).
I've gotta jump into the deep end of VOPS.
Thank you Mark

Sorry… very little VOP editing experience… I'm looking for a pointer (help) on how to add point Alpha recognition to an existing VOP network. I don't see this functionality in any of the shipped VOP materials (9.1.124).
Additionally, is there a way to incorporate “exist” type functionality in a VOP shader without using texture maps? Perhaps using the Alpha value of a point?
Thanks

Using H9.1.124
Here's a hip file with a simple Foreach attempt.
Just trying to transform each group by “FORVALUE”, and add random Cd to the points in each group based on “FORVALUE”.
Any help appreciated.

H 9.1.124
This is a simplified version of what I'm trying to do…
- Object with 10 groups… grp_1 … grp_10
- Feed into a Foreach sop
- Use a Point sop to add Cd to points in each group based on “FORVALUE”
I have not been able to find the appropriate syntax to get “FORVALUE” to work in the Point (and other) sop(s).
Any help appreciated.

H9.1.124
This seems like such a silly question, but for some reason I can't get a simple specular reflection map from a light to work.
Playing with a single object with super material shader and one light.
Have tried assigning a rat file to “Project Map” (which can't be right) of “Point, Spot, & Distant” lights, and also to “Area Map” of “Area Light”. Still not getting any specular reflections.
Surely I'm missing something very simple here.
