Hi,

I'm using C4D and Maxwell and I often got shading issues even when setting the phong tag to smooth to 5° and not the default 80°

.OBJ or .3DS ? Quads + tris or tris only ? Export ngon ?

I sometimes set export options like:

Angle: 5°
Divide all bigger than 5cm (for small objects)
Avoid ratio bigger than 10
Avoid smaller than .2mm
