Hi,

I'm trying to get the inverse camera matrix of the render basedraw for an animation export. I step through the animation keys of the active camera object:

  
doc->SetTime(bt); // Set Time to key->GetTime();   
doc->ExecutePasses(NULL, TRUE, TRUE, TRUE, BUILDFLAGS_0);        
EventAdd(); // don't know whether that's required in this case   
BaseDraw *bd = doc->GetRenderBaseDraw();   
Matrix m = bd->GetMi();   
...

The matrix won't change during animation. It keeps the values from the first frame! Do I have to send another kind of update message?

If I use the inverted global matrix of the camera object, it works, but I would prefer to use the matrix from the render basedraw.

I dunno if this will help or not, but after the EventAdd(), add this:

  
  DrawViews(DRAWFLAGS_FORCEFULLREDRAW | DRAWFLAGS_NO_THREAD, NULL);    // force completion of cache rebuild

...I use that sequence of calls when I'm dealing with animating the document.

OK, thanks. I'll try it tomorrow. But I dont't want the editor windows being redrawed since it's called very often.
