    Hi,

    how to check if the free student version is running? Is there an additional bit somewhere set?

    For an activated free student version check if SYSTEMINFO_SAVABLEDEMO_ACTIVE and SYSTEMINFO_STUDENT are set.

    The feature comparison page has:

    "Support of serial number dependant plugins"

    ...disabled / unavailable with the free student version. Does that mean that plugins using the "SNHookClass" are just not called/loaded?

    Good call, apparently SNHookClass hook is ignored by the student version. You need to check for student versions outside, e.g. in PluginStart().

    I guess my question/speculation was more to the point that if you do use the SNHookClass - for serialized license key control - that you wouldn't need to worry about it with the Student version, since the plugin would simply fail to load (assuming that you didn't want it to load).

    ie. Inside the PluginMessage() code, when: id == C4DPL_INIT_SYS, then you normally call resource.Init(), check for version type and (if appropriate) call your RegisterPLGNSerial() routine. That in turn calls (for example) pPlgSerial->Register(_SERIAL_PLUGID, SNFLAG_OWN);

    ...that call to (SNHookClass) 'Register()' should fail (return false) with the Student version, so your plugin would just not load (assuming you trickled the 'false' return back through to the C4DPL_INIT_SYS message response).

    Does that sound correct?

    EDIT: To be more specific... I'm assuming if you reply 'false' to the C4DPL_INIT_SYS message, that your PluginStart() routine would never be called... ?

    If you do want to have your (serialized) plugin work with the Student version, you'd have to look for the Student version type and use some other method of serializing your license key.

    I have a question.  Currently my plugins check for this condition:

    else if (stype & (SYSTEMINFO_SAVABLEDEMO|SYSTEMINFO_SAVABLEDEMO_ACTIVE))                    { GePrint("C4D Savable Demo");    serial = FALSE; }
    

    Will I need to change all of them to allow use of my plugins in the Student version?  And, does this only cover R13 (and possibly R14)?  Which exact version of R13, btw?

    Thanks,

    The student version adds only the SYSTEMINFO_STUDENT condition. SYSTEMINFO_SAVABLEDEMO_ACTIVE & SYSTEMINFO_STUDENT indicates an activated student version.

    Okay.  So I also need to check for SYSTEMINFO_SAVABLEDEMO|SYSTEMINFO_STUDENT in my plugins?

    Thanks,

    Yes, otherwise it will be handled like an activated demoversion.

    The free student version behaves like a demo version with the additional SYSTEMINFO_STUDENT bit. So it really depends on your serialization system if plugins are loaded or not.

    Thanks - I should be good then - since my (currently posted) plugins don't currently load in active demo versions - but it seems like that kinda screws Robert if (for example) he wanted to treat an 18-month activated free student/demo version separately from a 45-day free trial demo version.

    What I meant is that the free student version behaves the same as the demo version, except the SYSTEMINFO_STUDENT bit allows you to differentiate between demo and student version.

    ...in any "future" (or re-builds of existing) plugins you publish.

    EDIT: sorry, I was intentionally trying to be a little vague on this point, but to get to the point, any existing (already published) plugins will not know the difference in a 45-day trial demo version and a 18-month free student version.

    Yes, that's correct.

    As mentioned, it won't affect me personally and maybe this is too late to change (???) but effectively, Maxon has taken a publishing decision out of the hands of 3rd-party developers by implementing it this way (they've effectively forced a retroactive situation/publishing model on us - instead of allowing for a proactive decision to be made).

    It boils down to a question (what normally would be the 3rd-party developers' decision) of whether you want to "provide your plugins for free to students" ... or not.

    Each developer may have their own opinions - even on a per-plugin basis - but Maxon has just "given away" all those plugins, making that decision for them.
