SOFTIMAGE|XSI v.3.5 Known Problems and Limitations

New Mixer - Audio d&d rules

If you try to drag and drop an audio file on the same track as an audio file of different frequency or mode (stereo/mono), it is disallowed and you loose the display of the curve on the original clip.

DotXSI - When exporting scenes with long animation sequences, you sometimes get an 'Out of memory' message.

We are trying to improve the memory management of dotXSI export but will be a future project.  In the meantime, workaround is to export in blocks of frames or break up the scene into separate models and export them.

locked scene files are not invoking warning message

          Rep steps:
          1-Launch XSI on one computer, load a scene
          2-Launch XSI on a second computer and load the same scene= warning message appear, load anyway.
          3-Close XSI on the first computer, you still have the scene loaded on the second computer
          4-Restart XSI on the first computer, load the same scene= no warning message

IRIX : Window Focus problem (on top)

The transient explorer problem is a focus problem. If you set the focus policy to click to type, the problem is gone.  This problem doesn't happen on IRIX 6.5.5 (r11) only on IRIX 6.5.12 (r82). 

On LINUX, if, upon starting XSI, your fonts don't look ok, simply run the following commands in your xsi system shell and they will be reset:

xset fp default

xset fp rehash

User Preferences->Data Management->Recovery File: a message needs to be displayed when an invalid path was set.

What Happens: You are able to exit with no messages
Expected behavior: You should get a message saying you wrote an invalid path.

Right-clicking in image clip does not pop menu anymore

Note:  This is by design.  Without extended component selection you need to use alt+RMB on the clip to get the context menu.  Or just use extended component.

  Note:  The Chain Up Vector is not an XSI constraint, but a normal operator.  You remove it by removing the operator you can see nested underneath the Kinematic Joint property on which the up vec lives.  If you selected first bone on the chain to apply the up vector, go to the scene explorer (Selection scope) look underneath the Joint property and you will see the operator there.  You can then click and 
delete it.
            To remove an upvector constraint:
            1. Select constrained object
            2. Go to its Kinematic Joint properties in the Scene Explorer
            3. either freeze the operator or delete it

Browser : Refresh doesn't group an image sequence on generation correctly.

Note:  You need 2 XSI's running- 1 rendering.  The sequence group/folders are confused by the new files being created by the other XSI's render.  If you go up a level and then back down to render pictures you get a new folder.
[1..12].pic, [1...38].pic each time you do this.

Negative numbers allowed as identifiers (we shouldn't allow that)

Note:  If you name an object e.g. -23, you won't be able to use it with the expression op.

Note:  It is not recommended to create clusters and do topology operations when 'disable from here' is used on the stack.  

Shadow_Pass - Overrides alpha-transparency maps applied to objects' surface - material shader - no transparency

Note:  The shadow pass will override the Surface and Shadow inputs of the material shader thus any Alpha-transparency maps used to burn holes into surfaces will be ignored in the shadow pass, resulting in incorrect shadows on surfaces.

Note:  If an object in the scene has the same name as the scene name, both will clash if they are in the same name space.

SDK: PerlScript ( *.pls ) doesn't show up in open script dialog

Note:  The activeperl installation for .pls is a scripting extension, so it doesn't show up in the dialog if you have WinAmp installed.

Note:  You cannot unload shader DLL/DSO libraries from the Libraries dialog. If you want to replace the

library you must exit XSI first.

XSI: Linux: Shader wizzard does not work with Mozzilla..

Note:  The shader wizard only works with Netscape on LINUX. Netscape is not the default browser for Red Hat so you will need to download and install NetScape in order to use the shader wizard.

KinematicState-PutTransform frame doesnt work

Note:  You cannot set the transformation of an object at a different time other than the current time.

Hair | Collision type "XSI" Causes hair to jitter spastically when obstacle is in static position within hair

Note:  With the 'XSI' collision type, both objects need to be moving or you will have numerical problems.  Use the other collision types if this is the situation you are in.

Workaround:  Scripting. Adjust a parameter for any other axis to generate a command, and then adjust the command for the x axis:  

ie: SetValue "Passes.Default_Pass.Environment.transform.StaticKineState.sclx", 2

Bad refresh when clicking on points with the paint tool

Workaround:  Execute the following command : rm -rf ~/.sawfish
