Several render channels are available, useful for compositing tasks. You can enable the channels you need and choose the file format for each channel.
The output will be saved in the same directory as set in the Output options.
Aside from the usual standard channels, some other may need a more detailed description:
The following image gives you an idea of what the different channels from Maxwell look like and an example of the final image after compositing several of them together using Photoshop. Please see the page of each channel to better understand how to use the channels for compositing.
Choose whether you want your channels to be exported as independent files (Separate), or embedded as one single file (Embedded) in the formats that allow extra buffers, such as EXR or TIF. The Alpha channel can be embedded in the TGA, PNG, TIF and EXR formats.
During the render, you can display the specific render channels that you’ve requested by hovering over the channel buttons in the render view.
The icons represent:
R: Render channel
A: Alpha channel
S: Shadow channel
M: Material ID channel
O: Object ID channel
M: Motion vector channel
Z: Depth channel
R: Roughness channel
F: Fresnel channel
N: Normals channel
P: Position channel
If the Multilight feature is enabled, Maxwell exports all the shadow buffers corresponding to each individual light emitter separately during the same render process, as well as a shadow pass of all the shadows cast by each emitter “blended” together, giving an extraordinary control over the compositing during the post-production process. For example you can change the brightness of an emitter using MultiLight which could then brighten up the shadow cast by another emitter. The blended shadow pass image will take these changes into account. |
