those pesky normals are at it again!
I created a circle. extruded it on the z axis then extruded again and sized it in some to create a ring (for a circus). then hit smooth shading, as per usual.
when the smooth shading is introduced the normals just go crazy. ive hit flip and recalculate several times but it barely does anything.
i had this problem yesterday on a resized cube. all i did was resize it and hit smooth again.
these are just basic shapes. whats going on?
