    Hi,

    I have a small problem with Thinking Particles.

    I have a node with the following code. In the editor, it's all right, but in the (render-)preview they are gone. Do I have to send a significant signal when I edit / create / delete particles?

    TP_MasterSystem* t = GetTpMasterSystem(GetActiveDocument());
         LONG k = t->AllocParticle();
         t->SetVelocity(k,Vector(30));

    Thanks..

    Have you tried to send a MSG_CHANGE message to the TP_MasterSystem? Maybe it also needs an EventAdd().

    cheers,

    Hi!

    I tried EventAdd() and t->Message(MSG_UPDATE, test); No success.. :-(

    Hi!

    My particle-generator works. The problem is the "recalculation" when I make a jump in the timeline.

    Should this be calculated by my plugin or is it a small function that recalculates the path of the particles?

    Thanks....

    The problem still exists. Does anyone has an idea? That would be wonderful.

    Hi!

    There are small news. I looked after the issue again, and I noticed something, thats very interesting.

    TP_MasterSystem* t = GetTpMasterSystem(GetActiveDocument());
         LONG k = t->AllocParticle();
         t->SetVelocity(k,Vector(30));

    In the first post I used GetActiveDocument(). When I render the scene, the particles are created in the active Document, not in the document that is rendered by the picture manager.

    So, if I render the scene and click "play" the particles will be created in the active document.

    Is there a command like "GetActiveRenderDocument()"?

    Thanks a lot.

    Ah, yes GetActiveDocument() only gives you the document of the original scene. During rendering to the picture viewer the document is cloned.

    Where do you call the TP system? If it is in your node then try mynode->GetDocument() to get the document.

    cheers,
    Matthias

    Thats it! :)

    Now I know why some pointers like the BaseDocument are avaible as argument, too.

    Thank you.
