These courses should help you get up to speed in no time.
Blender's Generate modifiers are a subset of modifiers designed to create or generate new geometry within your 3D scene. These modifiers are incredibly useful for quickly adding complex and procedural details to your models, saving you time and effort in the modeling process. They can be applied to various types of objects, such as meshes, curves, and text, volumes and even Grease Pencil, although we will be focusing mainly on meshes.
*Geometry nodes is a topic unto itself and is not a part of this course. Don't fret, however - we have a course for that!
Blender's Deform modifiers are a group of powerful tools that allow you to influence the shape and deformation of 3D objects, typically by using other objects or control points. These modifiers are essential for creating complex and organic animations, as they provide non-destructive ways to bend, twist, and manipulate geometry.
The course is like a visual glossary for modifiers, and watching it through helped me understand how Blender behaves in more than just the modifiers category.
It's invaluable to know what a tool/setting does, instead of just blindly using sliders. This is 100% a course to come back and refer to on an "as needed basis".
It has examples of all of it in action, in some basic shape or form (spheres, cubes, monkey heads) and while some of them are not quite easy to imagine in a real-life practical application, eventually you see them being used in a random project and the light bulb goes off.
I wish we had this kind of in-depth explanation for other parts of Blender; thanks for doing this Paul! Maybe one day we can convince you to tackle the "Edit" modifiers list too.
Side note: if you are like me and watch mostly everything in 2x speed, don't it with this one! Short videos but very information dense. You'll thank me later.
