Bump showing in viewport but not in Arnold render


I have a grayscale bump texture going into a bump node and then into the Normal slot of the Arnold Standard Surface shader. For some reason it will only show in the viewport and not when I render. I have tried changing between srgb and raw for the texture, I have tried extreme values for the bump amount. The bump node is set to Bump. I have also tried both Maya and Arnold’s 2d bump nodes, Im at a loss. This is for a human face on a character and for some reason if I check the Thin Geometry box it will render the bump but it greatly darkens the entire face. I also tried using a normal map setting the bump node to tangent space normals as well as enabling export tangents on the geometry but it had the same result. Any ideas? :confused:


Still stuck on this if anyone can help :confused:


Have you tried aiBump node instead of maya’s standart bump nodes??
