If you need to open a file that uses this variable in a version of Maya before 2017, set the variable and save the file without the packing before opening it in an earlier version. Note: This packed format is not recognized by versions of Maya prior to 2017. This variable is applied every time a file is saved, so the behavior can be changed dynamically without restarting Maya. This applies to any attributes in a scene that have this multi-multi structure, not just skinCluster weights. However, this produced a large number of setAttr commands for a large number of vertices. These commands would have a small number of influences/values, for example: setAttr 1 2 3 4. Previously, this created a setAttr command in the mayaAscii or mayaBinary file for each element in weightList that would set weights for a single vertex. The packed blocks combine setAttr commands to set values for a range in the parent multi, for example, setAttr 4 1 2 3 4 4 5 6 7 8 4 8 9 10 11, which significantly reduce the number of setAttr commands needed for this type of data in the file. For example, skin weights which have an attribute structure like, storing weights per-vertex, per-influence. When packing is enabled, file sizes are smaller and load/save times faster for certain types of data. This variable disables packing of attribute data for Multi-Multi attributes into blocks. This variable addresses performance issues with scenes that contain many LOD Groups, as they trigger graph repartitioning whenever a camera is moved. Set this environment variable to 1 to stop the Evaluation Manager from rebuilding the evaluation graph each time the LODVisibility attribute changes. To disable it, set the value to 0 (zero) or leave it undefined. To enable this option, set the value equal to 1. MAYA_DISABLE_BACKSPACE_DELETE (Windows and Linux)ĭisables the functionality of the Backspace key. Set this environment variable to 1 to opt-out of analytics when starting Maya in batch mode. Enabling this variable removes the variability to guarantee a deterministic tangent value, but at the cost of slower performance. However, this introduces a small amount of variability in the result. Setting this variable to a value of 1 causes Maya to quite instantly without performing those steps.īy default, tangent calculation is multi-threaded. Ordinarily when a SIGTERM signal is sent to Maya's signal handler, it will attempt to save the scene and generate a crash report. MAYA_DEBUG_SIGTERM_AS_SIGINT (Windows and Linux) This file contains a detailed description of what Maya was doing when the failure occurred. When Maya encounters a fatal error, this variable writes a crash report file ( MayaCrashLog.log) to the directory specified with the TMP environment variable. MAYA_DEBUG_ENABLE_CRASH_REPORTING (Windows and Linux) See Cached Playback status line states for more information on Safe Mode. Set a value of 1 to have Cached Playback enter Safe Mode (Yellow warning status) whenever a scene containing Time Editor clips is loaded. Use this option to restore previous behaviour. Occasionally, shots created in the scene would connect to the Camera Sequencer node in a referenced file. Restores the previous licensing behavior of trying to recover a lost license for 15 minutes rather than the default Autodesk standard of two hours.
