There are a million videos on YouTube to get in to Blender. Finding the right one can be tricky.
Start with the beginner series below. This is a brilliant beginner series that introduces you nice and gently!
Box modelling is based on the idea that you can model anything from a simple primitive e.g., a cube, a sphere, or a cylinder).
Modelling modifies shapes by combining shapes and modifying them using a set of mathematical equations and algorithms.
The artist starts with a basic shape, then gradually adds more detail and complexity to the model until it is complete.
It is used in industries such as architecture, product design, engineering, and video game development.
While harder to learn at first, once you have the key skills, you can create all sorts of objects. They are much easier to modify at any stage as each part remains editable.
Sculpting takes a more artistic, freeform approach.
It uses virtual sculpting tools to push, pull, pinch, and carve shapes organically the way a traditional sculptor works with clay.
The artist starts with a virtual ball of clay and shapes it into the desired form
It is used in film, animation, and video game art design industries.
While easier to learn at first, creating quality outcomes is much more challenging and every creation is unique. It is harder to modify and change outcomes later as they are essenitally a single object.
