Hi all,
I have written some classes for special effects like ambient occlusion or shadow.
All those classes are using their own prerender cameras. The cameras use the initial draw callback for updating their view matrices by using the main cameras view matrix.
Unfortunately it looks like the rendered shadow/ ambient occlusion matrices correspond to the previous frame. So my guess is that the view matrix of the main camera isn't updated from the camera manipulator at the time of the callback.
Is there any better callback I can use for that?
