I'm trying to generate custom rays with a VideoPostPlugin but somehow my generated rays do not reach the renderer. What I tried was to send a MultiMessage to the corresponding GeListNode like for instance:
> VideopostCreateRay ray;
> ray.x = 0;
> ray.y = 0;
> ray.p.x = 0;
> ray.p.y = 0;
> ray.p.z = 100.0;
> ray.v.x = 0;
> ray.v.y = 0;
> ray.v.z = 100.0;
> Get()- >MultiMessage(MULTIMSG_BROADCAST,MSG_VIDEOPOST_CREATERAY, &ray;)
but with no effect. How do I get the ray to the renderer? The SDK reference says something about sending a message, but how and when? Or can somebody explain how the CylindricalLens plugin provided with C4D 10 works?

you must overload the virtual NodeData::Message method and then check for the MSG_VIDEOPOST_CREATERAY messsage (like if(type==MSG_VIDEOPOST_CREATERAY)... ).
Then cast the *data pointer to VideopostCreateRay and change the ray parameters (p and v) according to how you want the ray to be fired into the scene.
That´s at least how I would do it.

It works! This is a thought I didn't have, yet it is very logical -> the ray is already there I just have to change it!
Thank you for the enlightenment,

you´re welcome. Yep, most of the time Cinema 4D fills the according information (especially in Videopost and for rendering)and all you need to do is working with them.
Once you get the hang of it (if you are a c4d user yourself it´s easier) it will all get fluent pretty fast.
