RenderBOX is simply a rendering manager. This will help 3D and Compositing artists to track and manage there render sequences.
install renderbox and its plugins in you system. setup your scene file in blender/maya. submit render job from renderbox menu.
now open renderbox to see all queued jobs. right click and start your jobs.
you can stop render any time and it will start again from same frame where render aborted

In this video i will show you my another testing with arduino and Houdini.
This time i am using HC-SR04 ultra sonic sensor to get the data from real world and pass in Houdini parameter through custom Python Qt GUI.
Hello VFX Guys,
its time to play with some electronics circuits and connect to our software (Houdini, Maya, Nuke ,Realflow ) to receive and transmit real world data.
In this video I will show you my testing work of connect Houdini Light to real world light.
Check out the Video Attached Below:
for this testing i have used following
Arduino UNO
3 LED
3 220 ohm resistor
Linux CentOS 7
Arduino IDE
Python 2.7.8
PyQt4
Houdini 13
mxstudio led otl
Houdini Object Model
In this post we start PyQt user interface widget toolkit to create a custom user interface inside Houdini.
Houdini does not distribute PyQt4, so if it is not installed you need to install it to your Python distribution.
Lets See How to install and setup Qt and PyQt4 in Linux Centos.
Check Houdini Python Paths
Run in your Terminal- env | grep houdini
Now Understand about python versions-
Centos 6.5 ship with python 2.6
and houdini 13 ship with python 2.6 and python 2.7
so if you have working python version installed in computer than houdini takes system python version.
else houdini will use HFS python versions.
to use Houdini Python versions
You can set HOUDINI_USE_HFS_PYTHON to 1 in houdini environment.
open file /home/rajiv/houdini13.0/houdini.env
add following line: HOUDINI_USE_HFS_PYTHON = 1
Now you can see python2.7.5 in python shell of houdini.
but no PyQt4 modules for houdini.
Python 2.7.5 (default, Oct 24 2013, 12:22:56)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2
Houdini 13.0.481 hou module imported.
Type “help”, “copyright”, “credits” or “license” for more information.
>>> import PyQt4
Traceback (most recent call last):
File “<console>”, line 1, in <module>
ImportError: No module named PyQt4
>>>
if in your system have python 2.7 with PyQt4 installed.
than you can add PyQt4 path (/usr/local/lib/python2.7/site_packages) in houdini sys.path
you may get following Error
ImportError: /usr/local/lib/python2.7/site-packages/PyQt4/_qt.so: undefined symbol: PyUnicodeUCS2_AsLatin1String
To Fix This Issue you should recompile PyQt against Hython (Houdini Python)
The Process of Compile PyQt for Houdini 13 on Centos 6.5
## Install SIP cd /tmp wget http://sourceforge.net/projects/pyqt/files/sip/sip-4.16.2/sip-4.16.2.tar.gz tar xvf sip-4.16.2.tar.gz cd sip-4.16.2 hython configure.py –bindir=/tmp/Houdini_PyQt/bin –destdir=/tmp/Houdini_PyQt/lib/python2.7 –incdir=/tmp/Houdini_PyQt/include/python2.7 –sipdir=/tmp/Houdini_PyQt/share/sip make make install
## Install PyQt4 cd /tmp wget http://sourceforge.net/projects/pyqt/files/PyQt4/PyQt-4.11.1/PyQt-x11-gpl-4.11.1.tar.gz tar xvf PyQt-x11-gpl-4.11.1.tar.gz cd PyQt-x11-gpl-4.11.1
## edit the configure.py and add the python command:
## sys.path.append(‘/tmp/Houdini_PyQt/lib/python2.7’) just before the line import sipconfig hython configure.py –bindir=/tmp/Houdini_PyQt/bin –destdir=/tmp/Houdini_PyQt/lib/python2.7 –plugin-destdir=/tmp/Houdini_PyQt/plugins –sipdir=/tmp/Houdini_PyQt/share/sip –assume-shared make make install
Now copy /tmp/Houdini_PyQt folder to common location and add “Houdini_PyQt/lib/python2.7” in sys.path and add in PYTHONPATH
To Test PyQt4 in Houdini go to shelh and create new tool and in scripts window copy following code:
“””
This Python Script will display Python and PyQt Version Installed in Houdini.
“””
import sys
path = ‘/Houdini_PyQt/lib/python2.7’ # Add Houdini PyQt path here
if not path in sys.path:
sys.path.append(path)
import getpass
import PyQt4
import PyQt4.pyqtconfig
from PyQt4 import QtGui
PYQTVERSION = PyQt4.pyqtconfig.Configuration().pyqt_version_str
USER = getpass.getuser()
PYTHONVERSION = sys.version
app = QtGui.QApplication(sys.argv)
QtGui.QMessageBox.information(None, ‘PyQt Information’, ‘Hello %s\nyour python version is %s\n\nyour PyQt version is %s’% (USER,PYTHONVERSION,PYQTVERSION))
The WordPress.com stats helper monkeys prepared a 2013 annual report for this blog.
Here’s an excerpt:
The Louvre Museum has 8.5 million visitors per year. This blog was viewed about 130,000 times in 2013. If it were an exhibit at the Louvre Museum, it would take about 6 days for that many people to see it.
