The NVIDIA Ansel Utility is a package of console commands for the game The Witcher 3: Wild Hunt. You can use it as an alternative to the official player. It allows you to expand and streamline your workflow. You can use it to create your own custom environment presets and even use the built-in ones.

In addition, it can be used to spawn an NPC actor and manipulate its model, position, rotation, scale, and appearance. It also allows you to play particle effects on an NPC actor and player.
