Hmmm. Maybe I haven't explained my problem well. I'll try again.
In your example scene, I would like the grid to be black wherever the sphere intersects it. The scene posted does not seem to do this.

Houdini Lounge » Shader colour based on bounding box
- lor

Good Day Houdini gurus.
I would like to change the colour of a mantra surface shader based on whether or not it is inside a bounding box. if inside, i would like the colour to be zero black, otherwise white. I need to animate the position of the bounding box. I have been thinking about this and looking through the shader for some time. It is not readily apparent to me how to approach this problem.
Any thoughts on how to start would be most appreciated

Here's a tidbit from the Term 2 students at CG Masters in New Westminster. 8 students had 15 weeks to recreate 54 shots from scratch. All fx, shading, lighting, rendering done using Houdini/Mantra/HQueue.

Hello,
I am copying spheres onto particles. I would like to stamp the particle color onto the sphere geo but am having trouble. I am not sure what value to enter for my stamp variable. Any suggestions would be appreciated.
current scene attached with particle color varying over age.

Hmmm. Clearly this does work. What version of Houdini please?
Did you do anything other than turn on “export variable for each light”

Can anyone else confirm that “export variable for each light” in the ROP output options (extra image planes) is not working?
All image planes seem to render with all lights in them.
thanks

With Hqueue its possible to resume a failed render, for example if there is a power off? I don't know how to do that Hqueue always starts again from the initial frame and overrides all.
Thank you!!!
Reschedule the job. It will fail and frames that have already rendered, because the IFDs are missing, but that's OK, because the frames have already rendered. It should carry on with the remaining frames.
Hope that works for you

All your machines need installation in exactly the same location. The target HFS can be the path to the install, for example:
C:\Program Files\Side Effects Software\Houdini 12.5.316.22\
So this option is better than targeting a distro in the server machine? I suppose because it doesn't have to access to the network. Is it right?
Yes.

ACCESS DENIED ERROR SOLVED!!!!
Holy Crap.
You are an administrator with all privileges, yet you still get “Access Denied” errors. The issue is that Windows now installs with UAC (User Account Controls) enabled. Disable them. Once I did this, I was able to disable the windows hqclient service and now my farm is rock solid.
If you're having trouble getting a machine running take these steps:
1: log in to your render account
2. Check your services. Ensure that Hqclient is DISABLED
3. open a command prompt, navigate to c:\Hqueueclient\
4. enter: hqclientd.bat stop
5. Using windows explorer, go to c:\hqueueclient\ and delete any .pid files.
6. back at the command prompt, type hqclientd.bat start.
If hqclientd.bat is in your task scheduler and scheduled to run whenever your render account is logged in, your machine should now work reliably, automatically picking up frames as soon as it is logged in.
good Luck

I have a fully functioning Windows 7 HQueue farm now running. Here is what I discovered while setting it up:
1. Do NOT use the windows hqclient service. Use hqclientd.bat.
2. Create a separate render login with administrator privileges and access to the shared drive. (everybody logs into this when they leave for the day and/or this is what you use for dedicated render nodes)
3. While logged in to your special render login, create a basic task within the task scheduler to start hqclientd.bat upon login. Note that the field “Start in (optional)” is NOT optional. You must enter the full path to the batch file.
4. In the hqueue web interface, if a client reports *NEEDS UPGRADE* it means the windows hqclient service is running and the node will fail all jobs. Fix this by running hqclientd.bat found in the HQClient install directory.
5. Make sure all machines have the same install of Houdini in the same place
6. Make sure HQClient is installed in the same place on each machine
The rest of the set up is as per the manual.
I hope this is useful. It took many hours and many innocent lives to deliver this information.
