Deleting shaders

When deleting shaders in Hypershade, its shading group is not deleted. This may result in orphaned shading groups, or worse, whatever was assigned to that shading group now does not show up in software rendering, and only shows up as dense wireframe in hardware shading.

Workaround

To get around the latter problem of software and hardware rendering, reassign those objects to another shader.

Showing tabs

When flipping back and forth between showing top/bottom/both tabs, the view is not reset, and may mislead the user into thinking that whatever was visible in one of the tabs is now invisible.

Workaround

To resolve this, set View > Frame All for the problem tab.

Warning messages appear when importing scene files in Hypershade

When importing scene files containing mental ray nodes, you may see warning messages such as:

// Warning: 'Draft.message' is already connected to 'mentalrayItemsList.options'. //

These warning messages, about pre-existing connections between mental ray related node, are harmless and can be safely ignored.

A warning dialog box also appears when these warnings occur. If you are importing many files and wish to avoid manually closing the warning dialog box for every file, you may want to use the file command with -prompt false.
