Why it's useful

Most AI game-art workflows are built in it: sprites, textures, concept art, 3D models and more, by wiring models together in boxes. Thousands of free add-ons and shared workflows.

What it needs

A graphics card is strongly recommended. Each model you load has its own licence, so check the ones you use.
