Lens shader recalculation in IPR

[of-air]

hey,

first let me just say thanks for all for sharing your knowledge,
I learned alot.

ok, to my problem,
I created two shaders,the first acts as a lambert that outputs
frame buffers. and the second is a lens shader that let you
pick the frame buffer it will show.

what I want is to be able to change the number of frame
buffer I want it to output without rerendering the scene.

all of the FB data is there I just want it to show using the
IPR, every time a diffrent FB.

hope this makes sense and someone could help,
Ofer.

I didn't get what you're trying to do. sure I dunno what ya mean by 'all the FB data is there'. there're some fb data that could be read by imf_disp on render time but for that you'll need probably the integration library. also that fb stuff is generally deleted on the end of the rendering.

but probably you could achive something like you're after by using mr passes. you'll save the main pass with geometry and all of that. then you hide all the geometry and merge the pass you saved with the current scene, where you have just a lens shader to switch fb. fbs are saved with passes.
