Hi

This problem bothers me for so long and I searched everywhere on Internet still cant find an answer.
As shown in the Screenshot. The Disc circle light edge is so jagged, I cannot find a way to increase the segment for that circle.

My old way is just using a Disc primitive, then use a emission material, but it renders much SLOWER than Original Octane Area Light. So I tend to not do that and its not very convenient.
I tried change the area shape to Object, and use circle spline. But No Luck.

Please dev help a brother out, or maybe just add an option in the Octane light tag so we can change the segment to make it smooth. Thank you!
PS: Same goese to Cylinder and sphere

Another way is do as following screenshot, Manully make a Gradient texture to cover that Jagged edge. But it is still an annoying procedure. Time is money

Make a your own custom light source - polygonal.

Thank you! As I stated it already in the main thread, it tends to render much slower than just the Octane light, and not a good workflow since you need a seperate materail.

Use a rectangular area light with a circular shaped texture in distribution. That will give the fastest rendering time and works for most situations.

Thank you Jay! Yeah it is a nice workaround, I wish C4d can implement an advanced area light so we can tweak more

I get that this is the best option to use in this case, but doesn't this also 'waste' samples from the black part of the light? I once made a small spotlight which took way longer to render than other lights, and I thought this must be because of the amount of usable rays being way lower compared to a full white light texture/surface.
