Are there ever cases, when doing sophisticated layering of rendering like this, that you'd want to manually "kick off" the EffectCompositor for just a single frame and update the texture only once? (For example, by setting the NodeMask to 0xF for one frame, then back to 0x0 when you're done updating the View). Is there a term for this kind of approach, and would it make sense to also support this model of rendering directly or should it be left up to the user? > Thanks, > > Wang Rui > > 2012/9/11 Jeremy Moles <cubic...@gmail.com>: > > On Mon, 2012-09-10 at 22:57 +0800, Wang Rui wrote: > > This looks really cool so far.
