Like below picture shows, a good sss appearance was rendered by AlSurface, a shader of AlShaders for Arnold 4.2.12.2, on the left side. But a bad sss look with dark nose tip was rendered by AiSurface of Arnold 5.1 on the right, which has been constantly there in previous versions as well. The dark look will happen at tip part of object. The maya files are here as attachments. Could you please have a look. If any upgrade happens or solution is figured out, it must sssheadmayafiles.zipbe great. Thank you.
