For those using the new beta ...

This is a fantastic tip. I did a quick test and I am really impressed. It leaves me wondering why we haven't been told to do this before? I cant believe I just rendered a material with 256 subdivs in 3 minutes.

@OSN58 thanks for posting the comparisons.

How does this setup work with Catmull-Rom AA?

Although my color threshold to 0.003. does not go down that far. it only goes to 0.01...

That's odd, Kris. It should be able to go lower than that.

I suspect render time would go up a little.

But would the different type of AA affect the result - considering it's a sharpening filter...

Stinkie

Hm, I'm inclined to think the visual difference would be negligible, but then I don't know that much about AA filters. I usually sharpen in PS, if at all.

OSN58

Unfortunately, it only works with 256 subdivs, render speed in other cases less.

Stinkie

Still -pretty neat, huh?

Hi all,
Btw i tried your way as you described specifically to render hi poly car model (proxy) but the render times increased significantly

rspierenburg

I noticed the same as designo, increased render times with the new settings vs default.

I'm guessing it depends on the GI lighting... I tried this on an interior and my render times doubled. Seems to work fine on a simple exterior scene, but you need to decrease the reflection depth too to make it work. Otherwise, the reflection of reflections really bogs it down too. ymmv
