Just want to make sure I understand things...before I dig into this.
This assumes APP_CULL_DRAW and channel travMasks are set appropriately.
If I modify the traversal mask of a node in the CULL process to prevent
it from drawing that change propagates to the DRAW - right?
So, scene is culled with pfCull() then I decide not to draw something
that would otherwise. I flip the travMask of the node. The draw does
not draw the node.
The next frame I cull again. The travMask is not set because this is a
fresh copy from the APP. Then I can decide again whether or not to draw
the node.
In other words - the changes are only propogated downstream in MP mode
for the *nodes*. As opposed to the geometry where I would need to
explicitly use a cyclebuffer to isolate changes.
Is this correct? By default the scene graph propogates but not the
geometry without a cyclebuffer.
Thanks,
Scott
