### Instance Update Availability LightWave® 6.0 Component Layout, Modeler Header lwhandler.h A handler plug-in calls this to synchronize LightWave® with changes to the plug-in's instance data. LightWave® will refresh its own interface and will usually call the handler's evaluation function in the process. Global Call
       LWInstUpdate *instupdate;
       instupdate = global( LWINSTUPDATE_GLOBAL, GFUSE_TRANSIENT );
The global function returns a pointer to an LWInstUpdate.
       typedef void LWInstUpdate (const char *class, LWInstance);
The arguments are the plug-in class of your handler and the instance that has changed. Example Several of the samples, including blotch, inertia and txchan use the update function.
