?This set of plug-ins was created to improve the connection between Maxwell Render and Nuke, allowing Nuke to import MXI high dynamic layered renders, and adjust the light intensity and color in a similar way to the MultiLight feature in Maxwell Render.
It includes an MXI reader which allows Nuke to import and read MXI renders (with all the information contained in it, including independent emitters and render channels), an MXI mixer which mixes all the independent emitters' information into a single image allowing independent adjustment of each emitter intensity (to produce precise color correction during the compositing process), a MXI render node, which allows the user to resume the render from Nuke,

an MXI mask node, which creates masks based on the object/material ID buffers, and a Color Adjustments script, which allows intensity and color adjustment of each independent emitter present in the sequence, created to mimic the intensity and Color adjustment in MultiLight.
It is important to note that in order to get independent access to adjust each individual emitter, the render must be launched with the MultiLight feature on (although Color MultiLight is no longer needed). Be careful about using the color MultiLight feature, it generates a huge MXI and is not usable in Nuke. You only need the classic MultiLight.

Constant refinement

An interesting feature in Maxwell Render is the constant refinement approach of the render, which allows the post-production process to start while the render process is still going on, working in parallel and saving an extraordinary amount of time.
You can load your MXI render or sequence at a low level of quality (i.e at SL=4) and start the post-production process at this moment, while the render process continues.
Each time Nuke detects that the footage file has changed, it automatically refreshes it, showing you the latest and cleanest version available.

If you are a Maxwell Render license holder, then please access the Download Area through the Customer Gateway to download the plug-in. If you are not a license holder, then please download a free demo version of the plug-in at www.maxwellrender.com by filling out the application form.

Windows: Run the installer. Select the location/s where Nuke was installed.
Linux: Unpack the files. Go to the folder that corresponds to your version of Nuke. Copy the mxiReader.so, MxiMixer.so, MxiRender.so and MxiMask.so files to the Nuke plug-ins directory (Usually /usr/local/Nuke 6.1v2/plugins).
Mac OSX: Unpack the files. Copy the mxiReader.dylib, MxiMixer.dylib, MxiRender.dylib and MxiMask.dylib to the Nuke plug-ins directory (Usually /Applications/Nuke6.0v5-32/Nuke6.0v5.app/Contents/MacOS/plugins).

Note

Remember that you should have writing permissions and Administrator privileges to install the plug-in. If you do not have permissions, Nuke creates a directory in the user directory (Usually C:\Users\username\.nuke (Windows), /home/username/.nuke (Linux) or /Users/username/.nuke (Mac OSX)). You can install the plug-ins here. Make sure that the files are in the .nuke directory (not .nuke\plugins).

Tip

On Mac OSX the .nuke directory is hidden. You can open it using the following command in the terminal:

Code Block

open /Users/username/.nuke

Installing the Python Scripts

We have included some Python script commands with the plug-ins. They add a "Maxwell Utilities" menu in Nuke including all the features provided by the Maxwell Plug-in for Nuke.

Windows

Locate the Nuke user directory (usually C:\Users\username\.nuke). The installer has copied the following files here:

Panel

icons\maxwell_icon.png
python\maxwell.py
maxwell python commands.txt

Linux

Unpack the installer and copy the following files to the Nuke user folder (usually /home/username/.nuke):

Panel

icons (folder)
python (folder)
maxwell python commands.txt

Max OSX

Unpack the installer and copy the following files to the Nuke user folder (usually /Users/username/.nuke):

Panel

icons (folder)
python (folder)
maxwell python commands.txt

In the Nuke user directory you need to have the following files: menu.py and init.py. If either of them doesn't exist, just create it.
You must add the following commands to the menu.py file:

Code Block

import maxwell
nodesMenu = nuke.menu('Nodes')
newMenu = nodesMenu.addMenu('Maxwell Utilities', 'maxwell_icon.png')
newMenu.addCommand('MxiMixer', 'nuke.createNode("MxiMixer")', 'ctrl+m', 'maxwell_icon.png')
newMenu.addCommand('MxiRender', 'nuke.createNode("MxiRender")', '', 'maxwell_icon.png')
newMenu.addCommand('MxiMask', 'nuke.createNode("MxiMask")', '', 'maxwell_icon.png')
newMenu.addCommand('Reload All', 'maxwell.reloadAllReads()', '', 'maxwell_icon.png')
newMenu.addCommand('Reload Selected', 'maxwell.reloadSelectedReads()', '','maxwell_icon.png')
newMenu.addCommand('Color Adjustments', 'maxwell.mxihue()', '', 'maxwell_icon.png')

And the following commands to the init.py file:

Code Block

nuke.pluginAddPath('./icons')
nuke.pluginAddPath('./python')
