Talal Ur Rehman, the person behind the AboutOneMinuteTutorials on Youtube shows how you can use some clever techniques along with MASH in Maya to model a complex shape. The example shows you how to create a neat-looking twisted ring that incorporates some holes.
The run-through is a good example of how you can use Maya’s motion graphics toolkit MASH to assist with some modeling tasks. In this case, Talal uses MASH to place and replicate a strategically made component, into a long tube. Then it’s just a matter of deforming the tube shape into a torus.
AboutOneMinuteTutorials often shows some really clever techniques in Maya, and keeps most the videos just around a minute. Everyone has a minute!
