GD1
Game Development 1 (NABA, AY26-27). Install this one package and everything the course needs comes with it. Each lesson and each full scene is a sample: import the one the lesson names.
Install
In Unity: Edit → Project Settings → Package Manager → Scoped Registries → + — Name Petar Mavrodiev, URL https://registry.npmjs.com, Scope com.mavrodiev → Save. Then Window → Package Manager → My Registries → Petar Mavrodiev.
Also needed: the OpenUPM registry (for the volumetric fog)
Some samples use the CQF URP Volumetric Fog (MIT), which comes from OpenUPM. Add a second scoped registry in the same place: Name OpenUPM, URL https://package.openupm.com, Scope com.cqf.urpvolumetricfog → Save.
