View Full Version : Blurred Reflections are really quick!

I'm comping an ancient car model that I've got into some photies of my old house, and having a wee go at nodulating it's surface. Having just taken a stroll up and down, I thought I'd put some reflec-blur on the metal.

Didn't really seem to make much difference to the render times.

That's lovely, that is. :D

You're right! I don't use blurry reflections much, since they're so slow. But in v9 I'm finding that they render at least twice as fast - at least without antialiasing. Once I turned on antialiasing they rendered in about the same amount of time. Hmm.. more tests needed! :D

The awesome thing is we can now change the sample rate, and in most cases you can keep it quite low.

Ahh, and here I wasn't even using the nodal reflection shader. I was just comparing the standard surface reflection options. Using nodal for reflections is always faster than the old 8.5 reflection model.

Side note, I'm really impressed with the results from reflection dispersion. Very realistic looking. Way to go NewTek! I hope we see more innovation like this during this cycle...
