Hi!

Is there a way/function how we could avoid jaggy (aliased) edges on bright surfaces (reflections on a car and bright black body materials) in Octane rendering?

I tried to cover it by adding some bloom and glare but no luck it's still very visible.

Thanks

Those look like overbright values (so values over 1).

You can pull these areas back in, in compositing apps, but it'd be cool to have a clipping/burn/shoulder type function in Octane itself.

Perhaps you can also try use lower power emitters and add more exposure time or ISO in the scene. I am not sure if this could help.

Yes they are certainly over 1 (HDRI) but in LW native there is option called "limit dynamic range" which deals with that problem nicely. I hoped there is way to do it in octane somehow also.

thanks i+ll try lower value plus more exposure although i'm pretty high there also already .

Ok i dialed back black-body material for ceiling lights (it was 5.0 now it's 1.0), added bit more exposure and adjusted gamma but i still see same jaggy edges on lamps and reflections.

Hmm, what elee is there to try ?

All the scene looks a bit crisp. Perhaps you could add a bit of DOF effect, or change the "filter size" parameter (for example to 2.0) in the kernel to try to add more antialiasing to the scene.

Render at double resolution and scale down.

try the free OLMSmoother plugin - works really well in such cases.
