[max1e]

hi, i have question about edges. maybe its AA?

in attach image 2 example:
upper: cinema4d + octane
lower: cinema4d + vray

by vray image much smooth on edges. how i can render image in octane with smooth edges? on second image my octane settings. thanks

p.s. subscribers cant post in other forum section? its little bit strange

I don't quite get what you are asking, if it's about the round shader feature you can check that up per material in the common tab, If it's about alpha you actually want your alpha to look like that in the render that's called "straight" then in the compositing stage when you pre-multiply it you get a correct image without halos.
