Does anyone has any scene with a lot of noise from highly directional/IES lights? Can you share it with me?
What were you moving in that video? If it was a light being turned on/off then I would say this is normal because more lights = slower rendering. Also, what were your render settings?
Is it me or.. I never succeded in maknig work the displacement for my character in corona using the displacement option in the corona mtl... the mesh get hole.. and when I play with the water level it desappears..etc .. only problem.. I tried everything.. never work.. is bugged ??
