The Maxwell Render plug-in for After effects improves the connection between Maxwell Render and one of the most used post-production platforms: After EffectsEffects allows you to import MXI files (Maxwell Renders image format) into AE. The Maxwell Image file format is a rich container where large amounts of render data is stored. Each light buffer, alpha channel, Z-buffer and so on can be loaded from an MXI to an After Effects comp set. All channels generated by Maxwell Render can be loaded with After Effects from a single MXI file/sequence, like any other layered image format. One of the main advantages of the MXI format is that it stores all channels in 32 bits, so you can work using full range color always. In case that cases where the user doesn't need 32 bits of color, the plugin is able to retrieve all channels in 16 and 8 bits tooas well, maximizing the compatibility with the pipelines and plug-ins.
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 poor level of quality (for example, at SL 4) and start the post-production process at this moment, while the render process keeps going oncontinues. When you want to update the footage in After Effects to the last sampling level saved, replace the footage with itself (right-click on the footage, and select “Replace Footage --> File...”).
This allows the post-production and rendering process to work in parallel, creating a highly optimized workflow that saves a great amount of time.
Setting the project
To match the Maxwell Render quality and color configuration, you must set the color settings of the After Effects project with the following values:
- Depth: 32 bits per channel.
- Working space: Color space used in the Tone Mapping section in Maxwell Render (sRGB IEC61966-2.1 by default).
- Linearize working space: On.
Plug-in modules
The plug-in comes with two components: the MXI Reader and the MXI Extractor.
MXI Reader
The Maxwell Render image file reader for After Effects allows you to load MXI files or sequences as an After Effect footage into a 8/16/32 bpc projects. Simply import the MXI file(s) as you do with any other files in After Effects. That This way you can work with the render buffer of the MXIs like any other image format. It is not interesting. The In order to utilize the full power of the MXI format is in the amount of information that the
file have. To access that information and access all of the information the file format stores we need an additional component: the MXI extractor.
MXI Extractor
We can access all the MXI buffers using the MXI extractor. It is an effect plug-in, so first add your MXI footage into a comp, and then apply the “MXI Extractor” effect to the layer. Then, you can “extract” the buffer you want.

Extracting the environment light from an MXI
The “Channel” parameter allows you to select the buffer, and the “Light” parameter indicates the light buffer you want to use. Using the “Light” parameter only makes sense when you select “Light” or “Shadow” in the “Channel” parameter.

Channels available

in the MXI files:
- Render channel.
- Light channels (If if Multilight was enabled).
- Alpha channel.
- Object ID channel.
- Material ID channel.
- Shadow channel.
- Motion channel.
- Roughness channel.
- Z-buffer channel.
- Fresnel channel.
- Normals channel
- Position channel
Creating comps from
...
an MXI footage
The easy way to work with all the buffers is creating a folder containing all the data. Select the MXI footage in the project panel, and go to “File --> Create Maxwell MXI Comps”. That This action creates a folder in the project panel with the MXI footage name. Inside we can have 4 elements:
- A comp named “All layers” containing all the buffers that the MXI havehas.
- A folder named “Comps” containing all the buffers that the MXI have has separated.
- A comp named “Multilight” containing all the light buffers in “linear dodge” mode. Furthermore, the “Exposure” effect is applied to each light buffer to adjust the intensities easyeasily.
- A comp named “Multishadow” containing all the shadow buffers.

In Windows, when we create comps from a single MXI (not a footage) using “File --> Create Maxwell MXI Comps”, a dialog will appear asking for the duration of the comp in seconds. |
