How to get rid of black streak on mesh

[gookeeper]

Hi Peeps

I was importing an fbx file into 3ds and then applied a meshsmooth modifier, and noticed some black streaks on the model. i thought it was a import issue. so i created a new scene with just a cube and subdivided(tesselated) it. then applied the meshsmooth modifier and the same happens(it also renders the steak too). ive tried everything like smoothing groups, flipped normals, changing the graphic drivers. has anyone any ideas? ive not used max for a few years and wondering if something has changed.

the file is attached and an image.

Thanks

Guy

Hi. I think it's caused by your default light. Go to viewport configuration and change the default light from 2 to 1 (or the other way around depending on your actual setting).

Hope it helps
