VRay does not render dynamically-added objects

[lcrivell]

In my c++ plugin for Maya, I am creating simple Maya objects in the scenes at given times.
So for example when the animation reached frame 10 (timeChanged event), I execute

MGlobal::executeCommand("CreatePolygonSphere");

A sphere appears properly at frame 10, and when I render this frame, I can see it properly.
However, when doing an animation render from frames 8 - 15, the object will not appear on the render, just on the Maya UI.
How can I have Vray rendering dynamically-added objects ?

Thanks.

This is not how rendering works. Adding/removing objects in the scene is not animating. It can happen only in IPR mode. To be animation, you must change a parameter (like turning on/off the visibility).

Clear, thanks.
