temporarily General Override materials ?

Development Rendering

Hi,

i have a very complex scene with a lot of objects and materials, now i want to test my lightning and i’m looking for set all my objects with 1 neutral midgrey material (like i’m doing in CGI) for a better look at lightmass, lightning, umbra…

Is there a way to do that ?

Thank you

what stops you from using the different view modes for just that very thing?

ah yes, i didn’t notice that, lightning mode is great !
I just prefer doing my lightning with everything in grey (without color bleeding), and its faster to render
