After Effects

The Maxwell Render plug-in for After Effects 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. In cases where the user doesn't need 32 bits of color, the plugin is able to retrieve all channels in 16 and 8 bits as well, maximizing the compatibility with 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 continues. 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.

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. This way you can work with the render buffer of the MXIs like any other image format. In order to utilize the full power of the MXI format 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.

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 on the MXI files:

• Render channel.
• Light channels (If Multilight was enabled).
• Alpha channel.
• Object ID channel.
• Material ID channel.
• Shadow channel.
• Motion channel.
• Roughness channel.
• Z-buffer channel.
• Fresnel channel.

Creating comps from a 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 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 have.
• A folder named “Comps” containing all the buffers that the MXI have 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 easy.
• A comp named “Multishadow” containing all the shadow buffers.
