a pair of shaders to control interactively from within maya your framebuffers, store and write them out directly to img files.

*first collect the infos you need into separate buffers.

*then setup the buffer_write to write out the buffers to separate img files.

you can also 'break up' your scene lighting in different buffers and then recompose the whole after...
you'll just need a shader which has a way to link lights from its interface like the standard mib_illumin.

the up left and right are occlusion and specular buffers.
down left spot light with shadow.. right point'ambient' light.

great !

It's maybe asking a lot, but can you release the source code, or just the part that output the buffer to files ?

I think we need to start building a giant marble statue of Francesca so we can praise her greatness all day long!

Great work as always!!

The Ctrl_Buffer Tutorials have expired

Hi Francesca and all the Ctrl_Buffer users. I have followed this thread in search of a good tutorial for what is apparently a great MR Shader for Maya written by Francesca. Yet Francesca's video tutorials have all expired. I am especially interested with the tonemapper tutorial, but also wish to understand the overall use of this shader. Can Francesca, or one of the Ctrl_Buffer users, please post a link to these Ctrl_Buffer's tutorials. Are there any new updated tutorials?

Thank you in advance.

All the best,

i've searched ctrl_buffers for a function to deactivate maya's lights and default light - and activate other states in the Rendering Attributes, but i cannot find anything this way.
so you will get wrong results if you plug an ao pass in the ctrl buffers.
So you are not able to render more than one pass (for example just gi or just fg) - so the ctrl buffers do not make any sense.
instead of maya layering system - here you set a preset and it automatically deactivate the maya default lights and all other lights - for ao pass..

or am i doing something wrong?
