Hi guys! I need help. I'm a noob in compositing. But I need a dirty lens simulation. Something like this:
Plugin to simulate this effect, I have not found.
I have the idea to put a mask on top of a dirty lens and animate parameter blend.
But the light source on render a very dynamic (fire) so manually animate very difficult.
Please tell me how to to link a blend parameter to illumination? Or maybe you have other ideas. I would be very grateful.
