    DMM conflict in Maya 2014?

    Hello.
    I came across a strange problem that I'm not sure who's fault it is.
    The environment is Maya 2014 running under Win7 SP1 Ultimate. I'm using the DMM 1.1.8 trial.

    The conflict seems to be with Pulldownit 2.5 (demo).
    To verify, just open any sample DMM scene.

    Cases:
    A)
    1. Start Maya without DMM or PDI enabled.
    2. Enable both plugins (order makes no difference).
    3. Open a DMM scene, use it, start a New Scene.
    4. All's fine

    B)
    1. Start Maya with DMM only enabled.
    2. Enable PDI.
    3. Open a DMM scene, use it, start a New Scene.
    4. All's fine but sometimes same as in (C) below.

    C)
    1. Start Maya with both plugins enabled.
    2. Open a DMM scene.
    3. At the end of the scene load, in the Script Editor there's an extra line:
    Error: DMM: unknown plug
    4. You can use the scene but when you start a New Scene, Maya crashes.

    The error is 0xc0000374 - A heap has been corrupted
    OVERLAPPED_MODULE: Address regions for 'vray_Shave' and 'libfftw3f-3.dll' overlap

    I suppose it would happen at another point if VRay was not installed.
    I'm not sure what plugin might have added 'libfftw3f-3.dll' in the past (maybe Pulldownit?) but it's irrelevant.

    Question is where the 'unknown plug' message comes from (which plugin is DMM trying to get?) and why it behaves differently if the plugins are preloaded or not?

    It could very well be a PDI dormant error but since I installed DMM months after PDI and never had problems till now, I thought I'd ask here first.

    DMM works great in Maya 2014 by the way.

    Thanks.

    Problem resolved.

    I must have added Pulldownit in the DMM scene sometime in the past and forgot (probably in Maya 2013).
    This threw one or the other plugin off.

    Deleting all Pdi bodies from the scene, fixed the issue (though it shouldn't have crashed Maya to start with).

    Sorry for the false alarm.

    OK good. I checked the source code and the error you mentioned was the result of an invalid node connection to a DMM mesh.

    'Invalid connection' as in 'they did not do it right' or 'they did not do it the way DMM expects'?
    In either case, maybe you should talk to each other and exchange ideas.
    Plugins should cooperate properly or ignore each other gracefully. It's hard enough developing plugins of this type and 'strange' conflicts like this one should be reduced/eliminated.
    As a user, why enjoy one or the other if I can enjoy both?
