RELEASE NOTES FOR MARI 2.0v1

Mari 2.0v1

The Foundry

Known Issues & Workarounds

• BUG ID 15810 - The black borders at the edge of the canvas in

Perspective view are selected, if an object overlaps the borders when a

selection is made using the Marquee Select tool, with the selection mode

set to Magic Wand.

• BUG ID 16324 - Windows only: you cannot currently import an image

into a channel using a relative file path. To work around this, use an

absolute path when importing images.

• BUG ID 16616 - Python: PythonQt sometimes crashes when adding

temporary objects to layouts, or compound widgets such as

QTreeWidget. This is because of incorrect reference counting. To work

around the problem, always store a reference to every GUI item until you

are sure it is no longer needed.

• BUG ID 17618 - Ptex does not bake properly if the resolution of the face

is too small.

The work around is to increase the resolution of the selected faces you

are having problems with.

• BUG ID 17626 - It can take a long time to import very large or very high

polygon count Ptex models.

The work-around is to assign a small uniform face size (1x1 or 2x2) on

import, and then increase the resolution of the relevant bits of the model

as necessary after loading.

• BUG ID 17690 - The Tiled shader module and the Masked Tiled shader

module do not render correctly on Ptex channels. They are only intended

for use with a UV mapped object.

• BUG ID 18457 - Using “Fermi Series” NVIDIA graphics cards with drivers

older than version 270 results in various rendering issues when the

Virtual Texture Type is set to Half or Float.

To resolve this, please download and install the latest graphics driver for

your card from the NVIDIA website.

• BUG ID 19780 - Nuke<>Mari Bridge: A projector created in Ortho view

in Mari does not re-project correctly in Nuke.

• BUG ID 19829 - Nuke<>Mari Bridge: Unprojecting a displaced piece of

geometry does not project correctly in Nuke.

• BUG ID 20021 - Textures in the canvas intermittently switch between

lower and higher resolutions.

This issue is more likely to occur if your virtual texture resolution is low,

and you're working on a complex model with displacement. Possible

work-arounds include increasing your virtual texture size, reducing the

number of channels Mari has to access at once (for example, by reducing

the number of channels required for the current shader), to reduce the

patch resolution of patches in the channels used in the shader, or to use

a smaller canvas window or monitor.
