I would like to make sure that people know, who may be starting out using Lightwave, more specifically modeling, that it is never acceptable to have non-planar polygons on a model that will be in a final, rendered shot coming out of Layout (or any other package for that matter).
The most important reason for not having non-planar polygons is simple. At times, during rendering, the render engine may not know which direction the normal of a non-planar polygon is facing. Because of this “confusion” the renderer may have the normal facing one direction on one frame, and facing the opposite direction on another. What you see in the final rendered animation is a flickering polygon. Not good. Rendering = Time, Time = Money, Re-renders = More Money.
Having non-planar polygons, even ones obscured by other geometry, are not acceptable.
If you ever want to work in a production environment, as a modeler, your supervisor will check for non-planar polygons. It is “Modeling 101”. There are times when things may happen and you get a model that has non-planars because you are in a rush or for some other reason - but rest assured having them in your models will get you a visit or email from your supervisor. Having them all the time will reflect poorly on you.
Having clean models is essential in a production environment. Whether that production is at a large facility, or in your basement - the theories still apply.
