The Modeling Toolkit in Maya was a welcome and much needed addition. Over the last few releases however, it has undergone much better integrations and features, making it an amazing tool for Maya artists.
As an example, the Quad Draw Tool is a great way to not only start create models in Maya, but also as a retopology tool.Here, Patrick Woo gives an introductory look at using the Quad Draw Tool in Maya for retopologizing objects.
Patrick walks through how the Quad Draw tool works and how to use it with all of it’s features, and then goes on to show how to retopologize a model that has an uneven distribution of mesh details. In the end Patrick spends a bit of time talking about how Quad Draw can achieve proper edge flows.
