This is a follow-up tutorial (to Part 3 here) dealing with rendering spline-based objects as polygons when the object has a transparent and refractive material. It shows how to adjust the object to get the best possible appearance.
In the 3rd part of the the lipstick tutorial dealing with modeling, the clear plastic cap is examined for its potential to greatly impact render times. The lathe object is a spline based object and this can be slow to render when a refractive material is used. This tutorial shows how to render it as a polygon based object to get the best render time. A follow-up tutorial going into some further details regarding Render Splines as Polygons on objects with refractive materials can be found here.
In this second part of the lipstick modeling, we model the shaft or body part of the lipstick object.
This tutorial shows how to use boolean subtraction to help model the tip of lipstick.
This tutorial completes the modeling process for the beverage container lid.
In this modeling tutorial we create the upper part of the lid. As part of the modeling process the boolean subtract tool is used in a novel way to help create an inset region of the grip.
