Managing Ptex Faces

Once you have created the project and set the face texture options, a toolbar displays with a number of options for managing Ptex faces within your project.

Note:  When managing Ptex faces, please be aware that all image channels in your project share the same face texture resolutions.

With the Ptex toolbar you can:

• - Double the selected face resolution.

• - Halve the selected face resolution.

• - Set the world space face resolution for the selected face.

• - Set the face resolution for the selected face.

With the Selection toolbar, navigate to Fill to:

• - Fill the selected faces with the foreground color.

• - Fill the selected faces with the background color.

Note:  When adjusting the resolution of Ptex models, quad faces are limited to resolutions between 1x1 and 8kx8k, while triangular faces are limited to resolutions between 2x2 and 8kx8k.

You may notice a slight pause after adjusting the resolution of a selected face. This happens while Mari regenerates the texture’s proxy on the CPU.

Tip:  These options are also available in the menu bar under Ptex and Selection.

Within Preferences, it is possible to set the Minimum Size for face textures under Ptex > Face Textures | Minimum Size. The default quadrangular texture is 1 and the default triangular texture is 2. This represents the absolute minimum face texture size that Mari can restrict sizing operations to.
