Hi, I'm rendering shadows in karma using the 'backgroundplate' node, there are artifacts on the edges, I increase the primary sampling but they don't go away, can anyone tell me how to fix this? (Shadows from volumetric simulation)

Can you repeat the problem on a scene, and upload that? This image doesn't really give people a lot to go on. Something simple would be great. Also what version of Houdini are you running.
