Use the Profiling Center to monitor scene performance and pinpoint where performance cost is highest. You can access the Profiling
Center from the Window menu or by selecting System from the asset list in the Scene Browser .
The Profiling center is divided into four main areas:
- Rendering options
- Evaluation options
- Profiling Display Settings
- Setting options
- Profiling display
Rendering options
-
-
When active, Frustum Culling will prevent the rendering of anything outside the confines of the Viewer window. This option
is turned on by default. When this option is turned on, it appears in the evaluation line of the performance statistics, which
can be displayed in the Viewer window by using the Shift-F keyboard shortcut.
TipUse Ctrl-Shift-P to toggle the Frustum Culling setting on and off.
-
-
Evaluates tasks consecutively.
-
-
Evaluates nodes in a scene including all dependencies.
-
-
Evaluates deformation in parallel with other tasks. This option is turned on by default.
-
-
Allows you to switch between CPU and GPU skinning. GPU skinning is disabled by default on machines with four or more cores.
TipUse Ctrl-Shift-T to toggle the GPU Skinning setting on and off.
-
-
Displays the number of scene nodes being evaluated for each cycle.
-
-
Keeps the Viewer window in an always active state for a particular session only.
Consider that you are viewing an animation scene in the Viewer. When you open another application, for example Windows Explorer,
it opens up on top of the Viewer. Now the Windows Explorer is the active window and the Viewer window is inactive. This stops
playing the animation scene in the Viewer, keeping it in an idle state. You need to bring back the focus on the Viewer to
make it active and resume the play.
In the virtual production environment, it is important that the Viewer gets automatically refreshed when working with different
applications. To turn on the Always refresh viewer checkbox permanently, click the Save User Settings button in the Profiling
Center. This saves the setting to the MotionBuilder configuration.
Profiling Display Settings
Select from the following Display Details options to customize the Profiling display:
-
-
Shows a list of all the processes in the Profiling display.
-
-
Shows only the Eval process in the Profiling display.
-
-
Shows the Render process in the Profiling display.
-
-
Shows only the Devices process in the Profiling display.
Select from the following Profiling Mode options to customize the Profiling display:
-
-
All profiling is disabled, including Viewer profiling
-
-
Collects profiling for all known evaluation tasks. This is the default mode.
-
-
Collects profiling for all known rendering tasks.
-
-
Collects profiling for device input, device output and device evaluation.
-
-
Collects profiling for SDK.
-
-
Collects profiling for all known tasks that don't increase with scene size. For large scenes selecting this option will not
influence performance.
-
-
Collects profiling for all known tasks. For large scenes selecting this option will influence performance.
-
-
This option can be set to any value between zero and ten.
- Zero is a base level evaluation that is not dependant on a profiling mode.
- Ten is the deepest level of profiling available. Setting this depth could affect performance.
-
-
Setting this option to a value between zero and 200 denotes the sample size of evaluation cycles.
-
-
Toggle between two profiling time displays. Enabling this option shows profiling time in MS. Disabling this option shows profiling
time in reference to one frame.
Setting options
-
-
Saves your settings in a session.
-
-
Resets all your previous settings.
-
-
Restores the default settings that are in the configuration file.
