With the enhancements of technology, people are starting to upgrade their systems. This allows level designers and modelers to include many more polies into their creation with a minimal performance hit. Curves have become a common place, but more often than not, people do not implement them properly.

Here is a brief tutorial on how to do such:



You?ll note the ?wedge? method comes in contact with the outer wall in fewer instances, which leads to less splitting during the BSP process. And that?s a good thing (lower r_speeds). Of course, this is a simplistic example, but really helps when you have a curve with more faces.

Here is a basic example of how to do low-poly arches. This method can be used to hollow out cylinder, make doorways, and a number of other things.



One mustn?t forget the infamous 45-degree curve that you see very often in many maps. Most people, however, do it incorrectly and this leads the angled brush to appear skewed and makes it difficult to align a texture to. Here is a proper example.



Also, I thought I would note that the 'cylinder' tool in Worldcraft is not very efficient and often creates vertices that are not on the grid. For this reason, it is best to use the clip tool to create faces as you wish.
