This page explains the does, do not, and can do for curved objects. Traditionally curved objects work fine for ambient occlusion (ao). Inner occlusion on the other side ´sees´ (hits) the object from the inside, and finds obstacles. These obstacles do trigger streaks in a regular way.

  1. Do use inner occlusion with wide spread (90 degrees) - this works very well with curved objects.
  2. Do use ambient occlusion with any spread.
  3. Do not use streaks or up slope. Do not use very narrow spread (like 5 degree).
  4. You can try to suppress non-wanted streaks in up slope modus using the ´deg up´and ´deg down´ parameters.
  5. You can use splashes with wide spread and large streak size.
  6. You can use ´surface offset´ in the inclusion/exclusion rollup for streaks on slightly curved objects.
  7. You can use streaks or up slope on upright surfaces, like an upright cylinder.
