Known Issues and Workarounds

• MARI sometimes doesn't paint on first launch. This is because the Ambient Occlusion mask can be stuck on by default even when it is not available. To solve this, close MARI, delete the config file found in: ~/.config/TheFoundry/Mari.conf, and relaunch MARI.
• Painting with layers: Please refer to the Layers In Mari section in the MARI User Guide.
• The documentation lacks information on the Selection Groups palette. This palette lets you save selections of objects, patches, or faces. To do so, use the Select tool to make your selection and click in the Selection Groups palette. In the dialog that opens, enter a name for your selection and click OK. You can also use the other buttons on the palette to select, lock or unlock, and show or hide saved selections.
• BUG ID 10444 - UV layout: Your UV map must not be in the negative range or MARI will not import the model.
• BUG ID 10825 - The file browser doesn't always recall directories.
• BUG ID 10991 - The heads-up display (HUD) elements remain in UV View when switched off.
• BUG ID 11539 - Color Manager: Using Blur with other filters causes artifacts/corruption in the canvas. For this reason, we do not recommend using Blur together with other filters at this time.
• BUG ID 11874 - MARI doesn't recognize 3-digit padded OBJ sequences as animation.
• BUG ID 11902 - In the Projection palette, under Channel Mask > Mask Channel, there is currently no way to distinguish between the same channel in different objects.
• BUG ID 12023 - When changing the view, graphical glitches may appear in the canvas. To fix this, you can try increasing Gather Scale in the MARI preferences. This increases the buffer size MARI uses when gathering information on which image tiles are required for rendering the scene. A larger value may get rid of the glitches but also reduces painting and navigation speed.
• BUG ID 12102 - Current brush settings do not get saved as part of the project. Instead, MARI reverts to the default settings when you close and relaunch it.
• BUG ID 12244 - Selecting Channels > Import and Selected Only only works with sequences and not individual, named files.
• BUG ID 12480 - There are issues with some show/hide channel operations.
• BUG ID 12567 - Enabling Sync to VBlank in NVIDIA settings drastically hits MARI performance. If you experience very slow interaction, even with low-polygon models and a recommended graphics card, go to NVIDIA X Server Settings > X Screen 0 > OpenGL Settings and turn off Sync to VBlank. Then, restart MARI.
• BUG ID 12619 - If you have multiple objects in your project, creating a channel for all objects adds duplicate channels and causes problems in the Channels palette
• BUG ID 12665 - MARI crashes if it tries to autosave when you use the Towbrush tool in the Heal Selection mode and drag a selection around. The workaround for this is to turn the autosave off by setting Autosave Frequency to 0 in the MARI preferences, but if you do so, be sure to save your work often!
