Grab a free Peacemaker created by the artist for his tutorial on Cubebrush.
Here a little piece of the original interview about the gun:
For the Quad Chamfer operations, I used a third party script called “Quad Chamfer Modifier“ from Marius Silaghi, which has very handy options that are not available in the default 3DS Max Chamfer modifier.
I also highly recommend the AKM tutorial by Tim Bergholz / Chamfer Zone
Now this workflow is very simple to understand. You define the polygons through smoothing groups and after applying the Quad Chamfer modifier it adds additional chamfering at the edges at which the smoothing groups meet. Then applying Turbosmooth with two to three subdivisions will result in a nice Highpoly.
Here is our mesh with predefined smoothing groups, ready to make use of the Quad Chamfer modifier.
Now after applying the Quad Chamfer modifier, I set the option “Chamfer by“ to
“Smoothing Groups” to create supporting edges between the smoothing groups.
I also set the sharpness and iterations to “1“.
