Renders are showing some white connected pixels

[b.graaf]

We are creating some renders with the Arnold render engine, some Standard Surface materials and an Arnold Skydome light.

We are getting a white spot, existing of several pure white pixels (so no differente shades of white). It seems if there are some defect pixels in the display, or if those pixels have not been rendered at all.

Have you gone to that face (turn on the wireframe and find it) and checked to see if its normal is flipped? Have you checked its 5 verts to make sure they are welded to the ones they are coincident with? Lastly, do they have the same smoothing group and Mat ID as the surrounding faces?
