HDR Light Studio 4 - 3ds Max Live Connection (V-Ray RT)
3ds Max Live Connection Workflow
To launch the HDR Light Studio Live connection, press the new HdrlsLive button.
This opens HDR Light Studio Live and the HDR Light Studio 4 Live 3ds Max panel.
You can see hereActive connection with HDR Light Studio is working from the green tick.
In order for the Live connection to work, the Render Setup needs to be set toActiveShade and
V-Ray RT set as the ActiveShade renderer. Now the HDRLS panel shows the Current renderer valid.
Page 15
The Live connection works by linking HDR Light
Studios Live canvas data to the texture le
applied to the V-Ray Dome Light. When lighting
is changed in HDR Light Studio, it updates this
texture with a new tmp le. This changing tmp
le creates the interactive lighting experience.

16/23
HDR Light Studio 4 - 3ds Max Live Connection (V-Ray RT)
FInally make sure there is aV-Ray Dome Light in the scene, which should be set to Spherical (fulldome) on. This requires aVRayHDRI texture assigned to its texture slot. Now HDR Light Studio Live
has a texture slot on a Dome Light that it can connect to - Current environment hook valid denotes
it has found the Dome Light and texture.
Now all ticks are green and you are ready to use HDR Light Studio Live interactively to light a scene
with a session of ActiveShade using V-Ray RT.
Use HDR Light Studio to light your shot with interactive image based lighting. When you are happy
with the lighting, Render your nal lighting as an EXR or HDR le on disc. The Live connection will
automatically set this le to be used on the Dome Light. If you start adjusting the lighting in HDR
Light Studio, the Dome Light with revert to using tmp les again from the Live session and you will
need to re-render the le on disc in order for the texture slot to point to that.
The HDR Light Studio lighting design is embedded in the 3ds Max scene. If you Stop Live and close
the HDR Light Studio panel, you can open HDR Light Studio later inanother session and your lightingdesign will be loaded from the embedded data in the 3ds Max scene.
LightPaint Workflow
When using HDR Light Studio Live with V-Ray RT, users can also launch LiveLight by pressing the
Kettle button in the top bar of HDR Light Studio Live. Then your scene can be pushed from 3ds Max
into LiveLight to use the LightPaint feature, for point and click lighting on your model.
Please note: The Collada le format used to push the scene into HDR Light Studio does not support
V-Ray Physical cameras. There is a simple workaround, with the V-Ray Phsical camera used in a
view, right click on the Camera name top left of the view and change it to Perspective, then press
CTRL C and this duplicates the view exactly but as a normal 3ds Max camera. This new 3ds Maxcamera will be exported to HDR Light Studio.

HDR Light Studio 4 - Live connection for Maya
Live Plug-in Usage
This dialog is used to launch and select the connection for HDR Light Studio Live. With HDR Light
Studio Live, small temporary HDR les are sent to Maya with each change to the lighting design. This
provides an interactive lighting workow with instant updates in your IPR renderer - seeing the
lighting design in context on your nal scene. The plug-in works with Mental Ray, SprayTrace,
Maxwell, V-Ray, Renderman and Arnold.
Workflow
Step 1 - Open the HDR Light Studio Live dialog in Maya
Step 2 - AHdrlsProjectData node is created. The HDR Light Studio lighting design is now a part of
the Maya scene and embedded within this node.
Step 3 - Select your Host Renderer
Step 4 - The plug-in presents the user with suitable IBL nodes in the scene for that renderer, select
the Environment Hook from the drop down menu and HDR Light Studio Live will connect to that
with Live updates.
Step 5 - Press Start Live to launch HDR Light Studio Live with the live connection to the chosen
Environment Hook
Step 6 - The Direct Export plug-in can be used to push the same scene into LiveLight, so users can
use Lightpaint to place lighting directly onto the model and see the results update instantly in the IPR
window. This is a fast and precise way to light scenes.
Step 7 - When a production render is produced in HDR Light Studio Live, the le created is
automatically applied to the Environment Hook.

HDR Light Studio 4 - Live connection for Houdini
Live connection for HoudiniThe HDR Light Studio Live Controller (HDRLSLC) digital asset (HDA) can be used to interactivly in
realtime with Houdini to create image based maps for use with Environment Lights (EnvLights). Many
Env-Lights can be created and controlled with independently lighting setups from HDR Light Studio
to allow for later deep compositing. All projects associated with the lighting setup for each of the
scenes EnvLights are stored within the Houdini scene le so will be stored as the project le is saved.
Manual Installation Required
Install HDR Light Studio 4 using the installation files provided. Unzip the HDRLS_Plugins*.zip
file and find the Houini Live plug-in files required in the \HDRLS_Plugins\houdini folder.
To use the python binding with Houdini, the site-package les need to be made available for
importing into Houdini's python interpreter.
Copy into your python site-package search path for Houdini, or to the following default directories,
the contents of the site-package folder:
Windows: (Libraries compiled against python2.6 as shipped with Houdini12)
C:\Program Files\Side Effects Software\\python26\lib\site-packages\
Mac:/Library/Python/2.6/site-packages/
Linux: Your Python2.6 search path. Using the HDR Light Studio Digital Asset (HDA).
Workflow
The HDRLSLC HDA controls which EnvLights are being edited by HDR Light Studio at any one time.To use, make sure the HDRLSLC otl le is in your Digital Asset location.
Create an instance of the HDRLSLC HDA in the network view (under the digital asset section of the
tools menu).
Only one HDRLSLC is required, and it does not need to be linked to any other nodes in the network
view.
The properties of the HDRLSLC shows a single dropdown eld with all the scenes EnvLights - if none
are present, will be listed.
Also show are 2 buttons for starting and stopping the Live link to HDR Light Studio.
Select the environment light you wish to edit, then click on Start Live.
Pressing Stop Live at any time will close the HDR Light Studio editor.
Changing the selected Live EnvLight at any time will switch to the other EnvLights lighting design (the
current design will be copied over if no previous design has been associated with the new EnvLight).
The HDR Light Studio project associated with the EnvLight switched from will be saved in the
HDRLSLC, and recalled when the light is reselected
Once HDR Light Studio is running and connected to an EnvLight, realtime updates will be
automatically pushed through to the EnvLight.
Running the Render View set to Mantra's realtime preview will show the changing lighting in realtime
on your scene.
Once happy with the design, render out a Production Render to your desired asset location to
replace the low resolution realtime HDR image maps.
Please note: If you don't create a Production Render for any EnvLight, when next loading the scene
the texture will be the default red "missing texture" of Houdini as the lower resolution Live images are
