Disc light interpolation/smoothness

[ThomasMiller]

Is there a way to increase the smoothness of the edge of a disc light? I need a perfectly round reflection on a smooth object and I'm starting to notice the disc light's straight edges.

Adding a way to increase segments count like in Corona would be great.
in the mean time you might use a texture as a workaround

Thanks M.Max ! Very helpful. I figured I'd have to use a map but didn't realize I could use a gradient ramp like you suggested. Did you set the tiling to 1.1 so it would shrink down a bit?

You're welcome!
Yes I did increase the tiling to avoid the same issue when the jagged edges of the light still "cut" the texture . you could use a texture map of course, just make sure the edge is a bit blurry so you don't get any antaliasing issues.
