Example:ĬanAutoDefer adding this function to a plug-in you have to make sure that the plug-in actually supports deferral. You will also need to add this line to the *.DEF file. _declspec( dllexport ) ULONG CanAutoDefer() Let the plug-in register itself for deferred loading This function is called CanAutoDefer() and is an addition to the four other required DLL exported functions: LibNumberClasses(), LibVersion(), LibDescription() and LibClassDesc(). This is done by implementing a new function exported from the DLL itself. If a plug-in supports deferred loading it can let 3ds max automatically register it.

Typically the Registry entries are created by an installer program or by 3ds max itself if the plug-in supports AutoDefer, but in special cases they could be created by run-time code in a plug-in, or by manual use of a Registry editor. Disagreement can seriously impair the integrity of 3ds max itself.

(See details below.) This information must agree with the corresponding values returned by API calls to the plug-in itself. These entries contain critical information about each plug-in to be deferred, and about each 3ds max class implemented by each such plug-in.

is also saved, or at least deferred.ĭeferral is governed by entries in the Windows Registry. Time taken at startup to load the plug-in, assign its virtual memory, etc. The principal benefit of deferral is that the Windows resources used by the plug-in will not be consumed unless there is some specific use or interrogation of the plug-in. It might also happen when detailed information about the plug-in is requested. Each deferred plug-in will be loaded when and if needed, which will happen when one or more of the 3ds max classes implemented by the plug-in is actually created. It is possible to indicate to 3ds max that certain plug-ins should not be loaded at startup. See Also: Class DataClassDesc, Class ClassEntry.
