Once the custom channel has the required masks’ information, it can be exported via the export tab. The export panel is designed to help the users organize the masks’ information by optimizing file sizes, reducing memory usage, and saving multiple masks within the same texture map.
To export a texture with all the saved mask information, users can access the add map option by scrolling down to the end of the default texture maps list.
Mixer’s current export options allow users to customize channel packing using
- Export Resolution: 512, 1024, 2048, 4096, 8192 etc
- Multiple formats: tiff, exr, png, tga, jpg
- Multiple channels: Grayscale, R, G, B, A
- Multiple bit depths: 8, 16, 32
- Color space: sRGB, linear
- Value: export custom channel in either R, G, B, A, or greyscale
While selecting the file’s channels, the grayscale values will allow for a single channel in 8bit depth as the final output; however, selecting RGB or RGBA will allow for 3 or 4 more channels. The user can “channel pack” multiple masks in a single texture file using these channels.
In some cases, it will be useful to save an export preset that the user prefers in their workflow. This can be done by clicking the 3 dots icon on the top of the list of channels in the export tab.
