    Thanks for the quick reply Lennart.

    I'd be surprised, if this is the case though. I've got 3GB of RAM, I just have one default sphere which I'm applying it too, plus it crashes when the command is triggered the first time (i.e. just when I press 'execute' - I'm not running the playhead).

    This would be very disappointing too, as I was hoping to do some cool COFFEE powered animations, but if you can't do modeling commands on the fly, that sucks.

    Cheers

    Jon

    Try to put the coffee tag on a null object and the sphere as a child of the null.

    Then try to modify it. It´s not very clever to directly modify the scene object that your coffee tag is attached to! ;-)

    Also it may be possible that you need to use a copy of the document instead, but the former should work.

    Hey Katachi,

    are you saying I'm stupid?

    You're probably right!

    Now that you mention it, it makes sense not to have the Tag on a manipulated object and use a Null instead - so that's what I've done, and it works! Thank you Katachi for the quick, informed reply.

    So for anyone as dumb as me ;-) here's the code (applied to an inactive Null) :

    > \> main(doc,op) \> { \>      var obj=doc->FindObject("Sphere"); \>      var bc = new(BaseContainer); \>      SendModelingCommand(MCOMMAND_MAKEeditable, doc, obj, bc, MODIFY_ALL); \> } \>

    lol, I would never call anybody stupid except myself! :)

    Glad it worked out for you.

    Actually I would discourage anyone from modifying object/scene structures with a COFFEE tag. It's not really safe to add something to a scene's hierachy with a COFFEE tag for instance. For these things you should consider to use scripts or command plugins.

    Hi Matthias,

    Thanks for your reply.

    So I'd be best applying a script via the script manager?

    I've never used this before, but just tried after reading your response. My initial findings with the script manager are that it seems a script is only instigated via manually executing it, and also variable values don't appear to be retained upon subsequent execution. Is this correct?

    My experimentation here is with animation, so if my findings above are correct, then a COFFEE tag seems to be the only way to go i.e. use a COFFEE tag, and play through the timeline. I haven't had any problems with this (except for my issue mentioned above) - but you're saying I'd be likely to discover some instability if I attempt anything too heavy?

    Thanks!

    Jon

    Hi Jon, maybe you can tell me a bit about what you are trying to do with the expression.

    There are some things you shouldn't do in COFFEE expression tag. One of them is adding objects to a document. Another one is accessing files. For subsequent/continous generative purposes currently the only safe way is to write generator plugins in C++.

    cheers,

    Hi Matthias,

    my interest is to just experiment and produce some lovely scripted animations and see where it takes me. My first script creates about 3000(!) cubes randomly, and they are eased into place to form letters. All this on a COFFEE tag. I've rendered out the animation fine, no problems. Pretty basic at the moment but I wanted to take it further, integrating some dynamics into the equation and then who knows!

    From your response, I gather my expectations are too high for COFFEE? As I say, it's been fine so far, but I'm now frightened I'll soon be hit with problems if I push COFFEE much further. Should I abandon COFFEE then? Generator C++ plug-ins sounds a little scary!

    Thanks

    Jon

    As I said, creating objects through a COFFEE expression tag is not safe. A safe way to create objects is to use Thinking Particles. You can control the particle creation with a COFFEE Xpresso node for instance.

    cheers,

    Thanks Matthias, I'll investigate.
